With option K73, the 24 V DC supply is provided by a dedicated SITOP power supply unit.

K76
Auxiliary voltage generation in the Line Connection Module

Cabinet Modules require an auxiliary energy supply to function properly. This current demand must be included in the configuration and supplied from an external source. If an external supply is not possible, the required auxiliary voltages can be supplied by means of an Auxiliary Power Supply Module.

Alternatively, option K76 can be selected. This provides for generation of auxiliary voltages in the Line Connection Module. This is particularly advisable for smaller device configurations.

With option K76, the following auxiliary voltages are provided:

The supply for the auxiliary power supply system is connected at the auxiliary voltage module of the Line Connection Module.

K82
Terminal Module for controlling the Safe Torque Off and Safe Stop 1 safety functions

The terminal module controls the Safety Integrated Basic Functions Safe Torque Off (STO) and Safe Stop 1 (SS1) (time-controlled) over a wide voltage range from 24 V to 240 V DC/AC (terminology as defined in IEC 61800?5?2).

The integrated safety functions, starting from the Safety Integrated (SI) input terminals of the components (Control Unit and Motor Module), satisfy the requirements of EN 61800?5?2, EN 60204?1, DIN EN ISO 13849?1 Category 3 for Performance Level (PL) d and IEC 61508 SIL 2.

With option K82, the requirements specified in EN 61800?5?2, EN 60204?1, DIN EN ISO 13849?1 Category 3 for Performance Level (PL) d and IEC 61508 SIL 2 are fulfilled.

The Safety Integrated functions using option K82 are only available in conjunction with certified components and software versions.

The Safety Integrated functions of SINAMICS are generally certified by independent institutes. An up-to-date list of certified components is available on request from your local Siemens office.

K88
SBA Safe Brake Adapter, 230 V AC

The Safe Brake Control (SBC) is a safety function, which is used in safety-relevant applications, for example in presses or rolling mills. In the no-current state, the brake acts on the drive motor using spring force. The brake is released when current flows in it (low active).

The Safe Brake Adapter is already installed in the cabinet unit in the factory. An infeed is connected to terminal -X12 on the Safe Brake Adapter for the power supply. For control, a connection is established between the Safe Brake Adapter and the Control Interface Module in the factory using a cable harness.

On the plant side, to control the brake, a connection must be established between terminal ?X14 on the Safe Brake Adapter and the brake.

Description of the SBA Safe Brake Adapter > SINAMICS S120 chassis format units > System components > Supplementary system components.

K90
CU320?2 DP Control Unit (PROFIBUS)

Option K90 assigns a CU320-2 DP Control Unit incl. CompactFlash card to the Line Modules and Motor Modules. This unit handles the communication and open-loop/closed-loop control functions. DRIVE?CLiQ is used to establish a connection to the various modules and where required, to additional I/O modules. A PROFIBUS interface is available as standard for the higher-level communication.

The computational performance required from the Control Unit CU320?2 DP increases with the number of connected Motor Modules and system components – as well as the dynamic performance demanded.

Without performance expansion, it is generally possible to operate two Motor Modules with one Line Module.

The full computational performance of the CU320?2 DP is only available on systems with performance expansion (option K94).

Description of the CU320-2 DP Control Unit > SINAMICS S120 chassis format units > System components > Control Units.

K94
Performance expansion for CU320?2 Control Unit

With option K94, the CU320-2 Control Unit (option K90 or K95) is supplied with a CompactFlash card with performance expansion. This therefore provides the full computational performance of the CU320?2 Control Unit.

In addition to the firmware, the CompactFlash card also contains licensing codes that are required to enable firmware options, for example, the performance expansion and the Safety Integrated Extended Functions.

K95
CU320?2 PN Control Unit (PROFINET)

Option K95 assigns a CU320?2 PN Control Unit, incl. CompactFlash card, to the Line Modules and Motor Modules. This unit handles the communication and open-loop/closed-loop control functions. DRIVE?CLiQ is used to establish a connection to the various modules and where required, to additional I/O modules. A PROFINET interface is available for the higher-level communication.

The computational performance required from the CU320?2 PN Control Unit increases with the number of connected Motor Modules and system components – as well as the dynamic performance demanded.

Without performance expansion, it is generally possible to operate two Motor Modules with one Line Module.

The full computational performance of the CU320?2 PN is only available on systems with performance expansion (option K94).

L00
Use in the first environment according to EN 61800?3, Category C2 (TN/TT supply systems with grounded neutral point)

With option L00, the Line Modules have a line filter as well as additional measures installed in the factory; this means that the Cabinet Modules can also comply with the limit values for use in the first environment (Category C2) according to EN 61800-3.

Notes on the measures to be implemented by the customer are provided in the SINAMICS Low Voltage Engineering Manual.

In order to achieve the full filter effect, the optional line filter must always be used in conjunction with a line reactor.

Note:

Option L00 is not available for Line Modules in a parallel connection.

L07
dv/dt filter compact plus Voltage Peak Limiter

dv/dt filters compact plus VPL (Voltage Peak Limiter) limit the voltage rate-of-rise dv/dt to values of < 1600 V/?s and the typical voltage peaks to the following values in accordance with the limit value curve A according to IEC 60034?25: 2007:

• < 1150 V at U_line < 575 V
• <1400 V at 660 V < U_line < 690 V

The dv/dt filter compact plus VPL functionally consists of two components that are supplied as a compact mechanical unit, the dv/dt reactor and the voltage limiting network (VPL), which limits voltage peaks and feeds back the energy to the DC link.

It is so compact that it can be completely integrated into the cabinet, even for high power ratings. An additional cabinet is not required.

By using a dv/dt filter compact plus VPL, standard motors with standard insulation and without insulated bearings can be used with supply voltages up to 690 V in converter operation.

The power losses stated in system component section System components > Motor-side components > dv/dt filters compact plus VPL can be used to determine the total losses for engineering purposes.

dv/dt filters compact plus VPL are designed for the following maximum motor cable lengths:

• Shielded cables 100 m (e.g. Protodur NYCWY)
• Unshielded cables 150 m (e.g. Protodur NYY)

For longer cable lengths (> 100 m shielded, >150 m unshielded), the dv/dt filter plus VPL (option L10) should be used.

Notice:

• Operation with output frequencies <10 Hz is permissible for max. 5 min.
• The maximum permissible output frequency is 150 Hz.

When using dv/dt filters, restrictions regarding permissible pulse frequencies must be observed.

Please also note the relevant information provided in the SINAMICS Low Voltage Engineering Manual.

Note:

Option L07 cannot be combined with the following options:

• L08 (motor reactor)
• L10 (dv/dt filter plus VPL)

L08
Motor reactor

Motor reactors reduce the voltage load on the motor windings by reducing the voltage gradients at the motor terminals that occur during converter operation. At the same time, the capacitive charge/discharge currents that place an additional load at the Motor Module output when long motor cables are used are reduced.

Suitably dimensioned motor reactors or a series connection of several motor reactors make it possible to connect larger capacitances and thus allow the use of longer motor cables.

In the case of multi-motor drives, the use of motor reactors is recommended as a general principle.

The motor reactor is accommodated in the Cabinet Module. An additional 600-mm-wide cabinet located to the right of the Motor Module is only required for the chassis format in frame sizes HX and JX.

The power losses stated in the section System components > Motor-side components > Motor reactors can be used to determine the total losses for engineering purposes.

Note:

The terminal lugs of the reactors are not nickel-plated.

For Motor Modules in chassis format, the maximum cable lengths when using motor reactors are 300 m (shielded) or 450 m (unshielded).

For Motor Modules in Booksize Cabinet Kit format, by using motor reactors (option L08) the maximum motor cable lengths, specified in the following table, can be reached:

L09
Two motor reactors in series

With option L09 for Booksize Cabinet Kits, two motor reactors are used in series that can be located within the standard width of the Cabinet Kit.

The maximum permissible motor cable lengths when using option L09 are specified in the table under option L08.

Note:

The terminal lugs of the reactors are not nickel-plated.

L10
dv/dt filter plus Voltage Peak Limiter

A dv/dt filter plus VPL (Voltage Peak Limiter) limits the voltage rate-of-rise dv/dt to values < 500 V/?s and the typical voltage peaks to the following values in accordance with the limit value curve specified in IEC/TS 60034?17: 2006:

• < 1000 V at U_line < 575 V
• <1250 V at 660 V < U_line < 690 V

The dv/dt filter plus VPL functionally consists of two components, the dv/dt reactor and the voltage limiting network (VPL), which limits voltage peaks and feeds the energy back to the DC link.

Option L10 is installed in an additional cabinet with a width of 600 mm that is located on the right-hand side of the Motor Module.

By using a dv/dt filter plus VPL, standard motors with standard insulation and without insulated bearings can be used with supply voltages up to 690 V in converter operation.

dv/dt filters plus VPL are designed for the following maximum motor cable lengths:

• Shielded cable (e.g. Protodur NYCWY)
  • Motor Modules, frame sizes FX to HX: 300 m
  • Motor Modules, frame size JX: 150 m
• Unshielded cables (e.g. Protodur NYY)
  • Motor Modules, frame sizes FX to HX: 450 m
  • Motor Modules, frame size JX: 225 m

For cable lengths < 100 m shielded or < 150 m unshielded, the dv/dt filter compact plus VPL (option L07) can be used advantageously.

The power losses stated in the section System components > Motor-side components > dv/dt filters plus VPL can be used to determine the total losses for engineering purposes.

Notice:

• Operation with output frequencies <10 Hz is permissible for max. 5 min.
• The maximum permissible output frequency is 150 Hz.

When using dv/dt filters, restrictions regarding permissible pulse frequencies must be observed.
Please also note the relevant information provided in the SINAMICS Low Voltage Engineering Manual.

Note:

Parts of option L10 do not have nickel-plated copper busbars.
Option L10 cannot be combined with the following options:

• L07 (dv/dt filter compact plus VPL)
• L08 (motor reactor)

L13
Main contactor (for supply currents ? 800 A)

Line Connection Modules for current ratings up to 800 A feature only a manually operated fuse switch disconnector as standard. Option L13 is needed if a switching element is also required for disconnecting the cabinet from the supply (needed for EMERGENCY OFF). The contactor is controlled by the closed-loop control in this case. Option L13 can be ordered for Line Connection Modules together with Basic Line Modules (option L43). With Smart Line Modules and Active Line Modules, the contactor is included as standard.

L21
Surge suppression

In ungrounded IT systems, the line voltage is not permanently connected to the ground potential because of the missing ground connection of the supply network. Therefore, when a ground fault occurs during operation, a voltage against ground increased by a factor of 2 can occur. For this reason, it is recommended that a surge suppression against ground be installed for operation on IT systems. The surge suppression option includes the installation of line-side surge arresters and upstream fuses for each system phase. The signaling contacts for monitoring the surge arresters are connected in series and connected to a customer interface.

Note:

Option L21 does not include the components required to install an insulation monitor for the IT system. An insulation monitor should always be ordered separately as option L87 when the supplying IT system is not monitored at another position (e.g. at the transformer outgoing feeder). Only one insulation monitor can ever be used within the same electrically-connected network.
Option L21 also does not include removal in the factory of the metal bracket that makes the connection to ground of the radio interference suppression filter installed as standard. The metal bracket should therefore be removed during the installation or commissioning of the converter if the device is to be operated on an ungrounded IT system.

L22
Delivery scope without line reactor

The air-cooled Basic Line Modules and Smart Line Modules as well as the liquid-cooled Basic Line Connection Modules are supplied with line reactors as standard; the reason for this is that frequently in practice the line configuration at the connection point of the drive line-up and/or the line supply short-circuit power is not known.

If the supply is connected through a separate transformer or if the line has a suitably low short-circuit power or if the standard integrated line reactor does not need to be supplied for other reasons, then this can be indicated by selecting option L22.

In the case of air-cooled Cabinet Modules, option L22 can be selected for Line Connection Modules (rated current < 2000 A) in conjunction with Basic Line Modules (option L43) and for Smart Line Modules. In the case of liquid-cooled Cabinet Modules, option L22 can be selected for Basic Line Connection Modules.

For Basic Line Modules and Basic Line Connection Modules connected in parallel, a line reactor should always be used, i.e. option L22 cannot be selected.

The power losses of each line reactor stated in section System components > Line-side components > Line reactors can be deducted from the total power loss for engineering purposes.

For additional information, please refer to the SINAMICS Low Voltage Engineering Manual.

L25
Withdrawable circuit breaker

Line Connection Modules (air-cooled), Active Line Connection Modules and Basic Line Connection Modules (liquid-cooled) with an input current of > 800 A are equipped with fixed-mounted circuit breakers as standard. Where the customer requires a visible isolating distance, a withdrawable circuit breaker can be ordered as an option.

L34
Output-side circuit breaker

Option L34 can be used to disconnect the motor terminals from the Motor Module Chassis.

A rotating permanent-magnet synchronous motor generates a voltage at its motor terminals proportional to the speed. The motor terminal voltage is also available at the inverter output terminals as well as at the DC link and the components connected to it.

Option L34 is available for disconnection in the case of a fault or if maintenance work is to be carried out.

Option L34 is completely prewired and is accommodated in an additional cabinet, which is arranged at the right-hand side of the Motor Module (400 mm wide for frame sizes FX/GX, 600 mm wide for frame sizes HX/JX). It is controlled using a TM31 Terminal Module, which is included with this option. This means that the output switch is automatically controlled via the Motor Module.

Option L34 cannot be combined with the following options:

• L07 (dv/dt filter compact plus VPL)
• L10 (dv/dt filter plus VPL)

L37
DC interface incl. pre-charging circuit of the relevant DC link capacitance

If, for reasons relating to the process or availability, the Motor Module needs to be disconnected from the common DC link for an entire drive line-up or connected to it during operation, a manually operated isolating distance can be ordered as an option. With chassis format power units, this takes the form of switch disconnectors, and with Booksize Cabinet Kits, a contactor combination.

Option L37 is installed on the busbar between the Motor Module and the main DC busbar. To ensure that the module can be connected to a pre-charged DC link, the option also includes a pre-charging circuit for the DC link capacitors of the relevant Motor Module.

The switching operation is performed externally. The operating levers can be locked using a padlock (padlock not included in scope of delivery). The degree of protection of the cabinets is not influenced.

The air guidance contains option L37 and also option M60 (additional touch protection).

Options L61/L62 and L64/L65 (braking units) cannot be ordered together with option L37 for space reasons.

L40
Line filter monitoring

With option L40, the filter in the Active Interface Module is monitored for effectiveness against harmonic effects on the system. The capacitance of the filter capacitors of the integrated filter is continuously calculated and compared with the installed nominal capacitance by measuring the current and voltage in the Active Interface Module. If the calculated capacity deviates by more than the set tolerance, an alarm is triggered.

L41
Current transformer upstream of main circuit breaker

If additional current transformers are required for measuring or monitoring purposes, these can be ordered for (air-cooled) Line Connection Modules or (liquid-cooled) Active Line Connection Modules and Basic Line Connection Modules with option L41. The current transformers are installed upstream of the main circuit breaker in all three infeed phases.

The transformers have an accuracy class of 1.0. The secondary current is maximum 1 A.

The transformer measuring connections are routed to the terminal block in the Line Connection Module.

Note:

These current transformers are already included in options P10 and P11 (measuring instrument for the display of line values).

L42
Line Connection Module for Active Line Modules

Order code L42 is specified in the order to indicate that the Line Connection Module will be connected to an Active Line Module. The Line Connection Module is then adapted accordingly (pre-charging circuit, connection busbars, etc.). See also the information for the Line Connection Modules and the overview of options.

L43
Line Connection Module for Basic Line Modules

Order code L43 is specified in the order to indicate that the Line Connection Module will be connected to a Basic Line Module. The Line Connection Module is then adapted accordingly (line reactors, pre-charging circuit, connection busbars, etc.). See also the information for the Line Connection Modules and the overview of options.

L44
Line Connection Module for Smart Line Modules

Order code L44 is specified in the order to indicate that the Line Connection Module will be connected to a Smart Line Module. The Line Connection Module is then adapted accordingly (pre-charging circuit, connection busbars, etc.). See also the assignment table for the Line Connection Modules and the overview of options.

L45
EMERGENCY OFF pushbutton, installed in the cabinet door

The EMERGENCY OFF pushbutton with protective collar is installed in the cabinet door of the Line Connection Module and its contacts are connected to a terminal block. From here, the EMERGENCY OFF pushbutton can be integrated into the plant-side EMERGENCY OFF chain.

L46
Grounding switch upstream of main circuit breaker

The grounding switch is upstream of the circuit breaker in the Line Connection Module and short-circuits the incoming supply system to ground. The grounding switch is manually engaged using a rotary operating mechanism to ensure isolation from the line supply when maintenance is being carried out. Measures must be taken at the plant to ensure that the grounding switch cannot be engaged when voltage is applied.

It is also essential to ensure that the supply system cannot be connected when the grounding switch is engaged.

The signals required for mutual interlocking are available on the terminal block.

L47
Grounding switch downstream of main circuit breaker

The grounding switch is installed downstream of the circuit breaker in the Line Connection Module and short-circuits the incoming supply system to ground downstream of the main circuit breaker. The grounding switch is manually engaged using a rotary operating mechanism to ensure isolation from the line supply when maintenance work is being carried out on the converter.

In this case, the grounding switch and the main circuit breaker for the Line Connection Module are interlocked with each other, which ensures that the grounding switch cannot be closed when the main circuit breaker is closed.

If the grounding switch is engaged, it is interconnected to ensure that the main circuit breaker cannot be closed.

L50
Cabinet lighting with service socket

With option L50, cabinet lighting is included with an additional service socket for a SCHUKO connector (connector type F) according to CEE 7/4. The power supply for the cabinet lighting and the service socket is external and must be fuse-protected for max. 10 A.

The cabinet lighting consists of an LED hand lamp with On/Off switch and with magnetic fasteners with an approx. 3 m long connecting cable. The lamp is factory-positioned in the cabinet door at a defined marking, and the connecting cable is wound on the associated mount.

L55
Cabinet anti-condensation heating

The anti-condensation heating is recommended at low ambient temperatures and high levels of humidity to prevent condensation. Depending on the cabinet width, a 100 W cabinet heater is installed for each Cabinet Module.

1 heating element for cabinet width up to 600 mm, 2 heating elements for cabinet width over 800 mm.

The power supply for the anti-condensation heating (110 V to 230 V AC, at terminal block ?X240) must be provided externally and fused with max. 16 A.

L61, L62, L64, L65
Braking units

Braking units may be required for drives in which motors might operate in generator mode, but have no facility for feeding energy back into the supply system.

The braking unit comprises two components:

• A Braking Module that can be installed in the air discharge of the chassis format power units
• A braking resistor to be mounted externally (degree of protection IP20).

The braking unit functions as an autonomous unit, and does not require an external power supply. During the braking process, the kinetic energy is converted into heat in the externally mounted braking resistor.

A max. cable length of 100 m is permissible between the Braking Module and the braking resistor. This allows the braking resistor to be mounted externally so that heat losses can be dissipated outside the converter enclosure. The braking resistor is directly connected to the Braking Module.

For SINAMICS S120 Cabinet Modules the following braking modules are available, depending on the frame size:

P_DB: Rated power (continuous braking power)

P₂₀: 20 s power referred to a braking interval of 90 s

P₁₅: 15 s power referred to a braking interval of 90 s

If the braking units listed here do not provide adequate braking power, up to four braking units on a DC link busbar may be connected in parallel. Braking power can be shared among several Modules. In this case, a Braking Module is assigned to each braking resistor.

Note:

It is only possible to use a Braking Module, if a DC interface (option L37) has not been selected for the Motor Module.

When engineering the system, it should be ensured that the module in which the Braking Module is installed is switched on during braking so that the Braking Module is properly cooled. Failure to follow this instruction means that the Braking Module could overheat and shut down, the drive will no longer be able to operate in braking mode. In this case, the Braking Modules should preferably be located in the Line Modules.

Load diagram for Braking Modules and braking resistors

Additional notes about possible duty cycles of the braking resistors and other engineering notes are included in the SINAMICS Low Voltage Engineering Manual.

L87
Insulation monitoring

An insulation monitor must be used if the converter is connected to an ungrounded line supply. The device monitors the entire galvanically coupled circuit for insulation faults.

An alarm is output in the event of a fault.

Notice:

Only one insulation monitor can be used in each galvanically coupled network.

As there are different response strategies when a ground fault occurs in an ungrounded system, output relays of the insulation monitor are provided for integration in a plant-side control. It is also possible to integrate the outputs into the Cabinet Modules monitoring system on the plant side.

M06
Base 100 mm high, RAL 7022

The additional cabinet base allows larger bending radii for cables (cable inlet from below) and enables them to be routed within the cabinet base.

The cabinet base is supplied in RAL 7022 as standard. A special paint finish is not available for the base. It is delivered completely assembled with the cabinet. The height of the operator panel changes accordingly.

M07
Cable marshaling space 200 mm high, RAL 7035

M51
Motor connection wired to customer terminal

Option M51 is a meaningful add-on to option M77 (version without component support plates or additional control components).

With option M51, the connection of the motor cable is wired to a customer terminal ?X1 and thus makes the process of connecting motor cables easier.

Without option M51, the motor cable is connected directly to the Motor Module. In systems with one motor reactor or two series-connected motor reactors (option L08/L09), the motor cables are connected directly to the motor reactor.

M54
Degree of protection IP54 (for air cooling only)

Cabinet Modules with degree of protection IP54 are supplied with additional roof sections, plastic ventilation grilles, and a filter medium in the air inlet and outlet, which ensures compliance with degree of protection IP54. This increases the cabinet height by 400 mm. For transport reasons, the roof sections are delivered separately and must be fitted on site.

The filters must be maintained according to the local environmental conditions.

Notice:

• The roof sections are painted in RAL 7035 as standard. If a special color is requested for the cabinet (option Y09), the roof section is also painted in this color. The molded plastic parts (e.g. ventilation grilles) are in RAL 7035 and cannot be painted.
• For units with degree of protection IP54, it is important to observe the derating factor for output currents in relation to ambient temperature and installation altitude.

M55
Degree of protection IP55 (for liquid cooling only)

Cabinet Modules with degree of protection IP55 are supplied with closed doors and roof sheets (without additional roof section). Water jets from any angle are permitted. Because the cabinets are completely enclosed and there is no exchange of air with the environment, it is not necessary to clean a filter medium.

The derating data are provided in the derating characteristics for the liquid-cooled Cabinet Modules.

Almost all heat losses are dissipated into the cooling liquid.

M56
Reinforced mechanical design

This option includes a strengthened mechanical version of the cabinet and mechanical locking of the cabinet doors. To secure the converter to the floor, a welding frame (5 mm high) is supplied separately. This option is available for all degrees of protection.

Note:

Option M56 cannot be combined with option M70 (EMC shielding busbar).

M59?
Closed cabinet doors, air inlet from below through floor opening

If the Cabinet Modules are erected on a false floor or duct which forms part of a forced ventilation system, the modules can be ordered with closed cabinet doors. To ensure an adequate air inlet cross-section, the units are shipped without the standard base plates. In this case, the customer must ensure that no dirt/dust or moisture can enter the Cabinet Module. Cables must not be routed in such a way that they impede the flow of air through the cabinet floor opening. If the area beneath the Cabinet Modules can be accessed, the customer must provide touch protection.

M60
Additional touch protection

The Cabinet Modules are designed in accordance with BGV A3 as standard. With option M60, additional covers (out of reach) at accessible operator control and switching elements, are provided in the area of the AC and DC busbars and in front of the power unit.

Option M60 is already included in M23, M43, and M54 for the following Cabinet Modules.

• Line Connection Modules
• Basic Line Modules
• Smart Line Modules
• Active Line Modules with Active Interface Modules
• Motor Modules chassis
• Central Braking Modules
• Auxiliary Supply Modules

Liquid-cooled Cabinet Modules incorporate additional touch protection as a standard feature - it does not have to be ordered with option M60.

M70
EMC shield bus

The EMC shield bus is used to connect shielded line and motor supply cables. The shields can be applied over a large surface area with the supplied EMC shield clips.

M72
Quick-release couplings for water hoses (for liquid cooling only)

With option M72, the ports for connecting the water hoses to the power modules and heat exchangers are fitted with quick-release couplings. The quick-release couplings ensure that no liquid escapes during uncoupling.

The use of quick-release couplings makes disassembly of the power modules and heat exchangers easier.

M77
Version without component support plates and without additional control components

If electronic components (Control Unit, Terminal Modules, Sensor Modules) are not used in the Booksize Cabinet Kit, the mechanical component support plates are omitted with option M77, including the customer terminal blocks for connecting motor cables.

The motor cables are then connected directly to the Motor Module in booksize format.

When option L08/L09 is used (motor reactor / 2 motor reactors in series), the motor cables are connected directly to the motor reactor.

The table below provides an overview of possible motor cable connection cross-sections for motor cables connected directly to a Motor Module in booksize format:

Note:

When combined with option M51, the motor connection is wired to a customer terminal.

M80 to M87
DC busbar system

The correct DC busbar for the Cabinet Module must be ordered. This is fitted in the upper section of the Cabinet Modules and connects the Line Modules to the Motor Modules.

The busbar is dimensioned according to the load requirements and demand factor associated with operation of the individual drives, and according to the specific Cabinet Module layout. For this reason, the DC busbar is not supplied as standard, but must be ordered as an option.

When selecting busbars, it is important to ensure that the systems of adjacent Cabinet Modules are compatible with one another (refer to the table below and option selection matrix for the Cabinet Modules in question).

Where Cabinet Modules are ordered as a factory-assembled transport unit with option Y11, all busbars in the transport unit must be identical.

The DC busbars are nickel-plated as standard and are available in different designs for a variety of current-carrying capacities. The scope of delivery also includes the jumpers required to link the busbar systems of individual Cabinet Modules.

M88
DC busbar system for line-side Cabinet Modules (for liquid cooling only)

Option M88 is required if Motor Modules are to be installed to the left or if up to four Basic Line Connection Modules or Active Line Connection Modules are to be connected for a parallel connection.

For this purpose, DC busbars are built into the upper part on the left hand side in the line-side Cabinet Module of each Active Line Connection Module and Basic Line Connection Module.

The busbars are nickel plated as standard and are selected for different current carrying capacities as for the selected options M80 to M87.

M90
Crane transport assembly (top-mounted)

A top-mounted crane transport assembly can be ordered as an option for Cabinet Modules.

Depending on the width of the module, it consists of either transport eyebolts (width ?800 mm) or transport rails (width >800 mm).

When Cabinet Modules are ordered as factory-assembled transport units (option Y11), they are shipped with transport rails, i.e. option M90 is automatically included in the scope of delivery of option Y11 and does not need to be ordered separately.

M91
Marking of all control cable conductor ends (incl. customer-specific wiring)

When this option is selected, all control cables or conductor ends (including all customer-specific options) are labeled throughout the cabinet.

N52
DC link fuses

The Basic Line Modules (air-cooled), Active Line Connection Modules and Basic Line Connection Modules (liquid-cooled) come without DC link fuses as standard.

If fuses are required, they can be ordered with option N52. The fuses are mounted on the connecting rail to the DC busbar in the cabinet rather than in the power unit.

The use of DC link fuses is recommended when Basic Line Modules, Active Line Connection Modules, and Basic Line Connection Modules are connected in parallel.

The Motor Modules contain DC link fuses as standard.

P10
Measuring instrument for line values, mounted in the cabinet door

A measuring instrument with display, installed in the cabinet door of the Line Connection Module, for acquiring measured values of the power supply. In addition to these measured values, additional plant values (such as power and power factor, etc.) are calculated from the measured values using powerful, state-of-the art microprocessors.

Current transformers (option L41) are already included in the scope of delivery.

P11?
Measuring instrument for line values with PROFIBUS connection, mounted in the cabinet door

A measuring instrument with display, installed in the cabinet door of the Line Connection Module, for acquiring measured values of the power supply. In addition to these measured values, additional plant values (such as power and power factor, etc.) are calculated from the measured values using powerful, state-of-the art microprocessors. The measuring instrument has a PROFIBUS interface that permits a data transfer rate of up to 12 Mbit/s.

Current transformers (option L41) are already included in the scope of delivery.

T58, T60, T80, T83, T85, T91
Rating plate data

The rating plate is provided in English/German as standard. A rating plate in another language combination can be selected by specifying the following option order codes.

W01
Partially redundant cooling unit with 2 pumps

The Heat Exchanger Module is equipped with a pump and a plate-type heat exchanger as standard. With option W01, two redundant pumps with two dirt traps are fitted: The pumps, which operate alternately, pump the hot coolant of the internal deionized water circuit into the plate-type heat exchanger and there it is cooled by the raw water of the plant-side cooling circuit.

System reliability is increased as a result of the alternating operation of the redundant pumps. In addition, the dirt traps can be cleaned independently and during operation.

W20
Raw water connection from the bottom

The raw water from the supply is fed into the Heat Exchanger Module from above as standard. With option W20, the Heat Exchanger Module has its port for the raw water underneath.

Y09
Special cabinet paint finish

The Cabinet Modules are delivered in RAL 7035 as standard. The special paint finish must be specified in plain text when ordering. Any RAL colors that are available as powdered coatings can be selected.

Notice:

If options such as cable marshaling space (option M07), top or drip protection covers (option M21) or roof sections (options M23/M43/M54) are ordered for the Cabinet Modules, they will also be supplied in the paint finish specified for the cabinet in the order. The molded plastic parts (e.g. ventilation grilles) are in RAL 7035 and cannot be painted.

Y11
Factory assembly into transport units

With this option, Cabinet Modules can be ordered as factory-assembled transport units with a maximum total width of up to 2400 mm. In this case, the relevant modules are shipped as interconnected units (both electrically and mechanically).

When DC busbars (options M80 to M87) are selected, it must be ensured that identical busbars are installed within the transport unit and are compatible with all adjacent Cabinet Modules.

In the case of a transport unit order, all the Cabinet Modules to be included in the unit and their installation sequence from left to right must be specified in plain text according to the syntax below:

In the case of air-cooled Cabinet Modules, option Y11 is recommended when creating units comprising Line Connection Modules with Line Modules because the required pre-charging circuits and connection busbars, for example, can be incorporated for certain versions. Please refer to the assignment tables for the Line Connection Modules.

With liquid-cooled Cabinet Modules, option Y11 is especially recommended to reduce the number of connection elements used in the cooling circuit on the converter side. It results in lower resistance to flow and avoids leaks.

The transport unit is shipped with a crane transport rail, which means that option M90 is not required.
