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

The terminal module is used to control the "Basic Safety Functions" over a wide voltage range from 24 to 240 V DC/AC. This means that the "STO" and "SS1" safety functions can be flexibly controlled from the signal voltages in the plant.

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 (previously EN 954‑1) as well as Performance Level (PL) d and IEC 61508 SIL 2.

These Safety Integrated functions of the SINAMICS S120 are generally certified by independent institutes. An up‑to‑date list of certified components is available on request from your local Siemens office.

With option K82, the requirements specified in EN 61800‑5‑2, EN 60204‑1, DIN EN ISO 13849‑1 Category 3 (previously EN 954‑1) as well as 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 following Safety Integrated functions are controlled using option K82:

• Safe Torque Off (STO)
• Safe Stop 1 (SS1)
  (time‑controlled)

With the Motor Modules in chassis format, option K82 cannot be ordered together with option L55 (cabinet anti‑condensation heating).

L08 Motor reactor

Motor reactors reduce the voltage stress on the motor windings by reducing the voltage gradients at the motor terminals that occur when motors are fed from drive converters. At the same time, the capacitive charge/discharge currents that occur at the converter output when long motor cables are used are reduced. Suitably dimensioned motor reactors or series connections of motor reactors therefore offer a solution which allows a higher capacitance and thus also longer motor cables to be connected. It is generally recommended that motor reactors are used in the case of multi‑motor drives. With option L08 for Motor Modules, a motor reactor is integrated, fully wired, into the Motor Module up to cabinet size GX (outputs of less than 315 kW). Due to space constraints, a separate cabinet must be planned for the output range 315 to 450 kW (cabinet size HX; see Motor Double Choke Module).

L25 Circuit breaker in a withdrawable unit design

Line Connection Modules 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.

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 or connected to the common DC link for an entire drive line‑up 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. Option L37 is installed on the busbar between the Motor Module and the main DC busbar. This option also includes a pre‑charging switch for the DC link capacitors of the relevant Motor Module so that it can be switched in to the pre‑charged DC link. 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 affected.

L42 Line Connection Module for Active Line Modules

Option 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.). Also refer to the assignment table in the "Line Connection Modules".

L45 EMERGENCY OFF pushbutton in 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.

L55 Cabinet anti‑condensation heating

The anti‑condensation heating is recommended for 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. One 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 to 230 V AC, at terminal block -X240) must be provided externally and fused with max. 16 A. Within the transport units, the heaters are internally connected and must only be fed once. Option L55 cannot be ordered together with option K82 (terminal module for the control of safety functions).

L87 Insulation monitoring

An insulation monitor must be used if the converter is operated on an isolated supply system. The device monitors the entire galvanically coupled circuit for insulation faults. An alarm is output by the insulation monitor in the event of a fault.

Notice:

Only one insulation monitor can be used within the same electrically connected supply system. As there are different response strategies when a ground fault occurs in an isolated supply system, output relays of the insulation monitor are provided for integration in a line‑side control. It is also possible to integrate the outputs into the monitoring system of the Cabinet Modules on the line 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 in all cases. A special paint finish is not available for the base. It is delivered completely assembled with the cabinet.

M07 Cable compartment 200 mm high, RAL 7035

The cable compartment is made of strong sheet steel and allows cables to be connected more flexibly (entry from below). It also allows routing of cables within the compartment. It is delivered completely assembled with the cabinet.

Notice:

The cable compartment is painted as standard with RAL 7035. If a special color is requested for the cabinet (option Y09), the cable compartment is also painted in this color.

M21 IP21 degree of protection 

Cabinet version in IP20, but with additional roof or canopy. This increases the cabinet height by 250 mm. For transport reasons, the roofs or canopies are delivered separately and must be fitted on site.

Notice:

The roof or canopies are painted with color RAL 7035 as standard. If a special color is requested for the cabinet (option Y09), the roofs or canopies will also be painted in this color.

M23 IP23 degree of protection 

Cabinet Modules with IP23 degree of protection are supplied with additional hoods, plastic ventilation grilles, and a filter medium in the air inlet and outlet. This increases the cabinet height by 400 mm. The filter medium must be maintained according to the local environmental conditions. For transport reasons, the hoods are delivered separately and must be fitted on site.

Notice:

The hoods are painted with color RAL 7035 as standard. If a special color is requested for the cabinet (option Y09), the hood is also painted in this color. The molded plastic parts (e.g. ventilation grilles) have color RAL 7035 and cannot be painted.

M26 Side panel (right)

For side‑by‑side installation of Cabinet Modules from left to right, cabinets can be ordered ready‑prepared at the factory for assembly on‑site. If option M26 is ordered, the Cabinet Module is shipped with a side panel fitted on the right. This side panel is essential for ensuring compliance with IP20 and higher degrees of protection.

M27 Side panel (left)

For side‑by‑side installation of Cabinet Modules from right to left, cabinets can be ordered ready‑prepared at the factory for assembly on‑site. If option M27 is ordered, the Cabinet Module is shipped with a side panel fitted on the left. This side panel is essential for ensuring compliance with IP20 and higher degrees of 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.

M70 EMC shield bus

The EMC shield bus is used for the connection of line and motor shielded power cables. The supplied EMC shield clamps provide a large surface area for the connection.

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.

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 (order code 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.

Y09 Special paint finish for cabinet

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

Notice:

If options such as roofs or canopies (option M21) or hoods (option M23) are desired for the Cabinet Modules, these are also painted in the ordered cabinet color. The molded plastic parts (e.g. ventilation grilles) have color RAL 7035 and cannot be painted.

Y11 Assembly into transport units at factory

With this option, Cabinet Modules can be ordered as factory‑assembled transport units with a maximum 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 for these "units", 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:

Option Y11 is particularly recommended for units comprising Line Connection Modules and Line Modules because the required pre‑charging input circuits and connection busbars, for example, can be incorporated in the transport unit for certain versions. Please refer to the assignment tables in "Line Connection Modules". The transport unit is shipped with a crane transport rail, which means that option M90 is not required.
