Motor connection and connenction boxes

Connection, circuit and connection boxes

Location of the connection box

The connection box of the motor can be mounted in four different locations or positions. The position of the connection box must always be viewed from the drive end (DE). The standard position of the connection box is on top, with the exception of non-standard motors in which case the standard position of the connection box is on the right-hand side.
Connection box on right-hand side Order codeK09
Connection box on left-hand side Order codeK10

If rotation of the connection box is possible later for motors that are supplied as standard with cast feet, it is recommended that the version Connection box on top, feet screwed on is recommended.
Order codeK11

The number of winding ends depends on the winding design. Three-phase motors are connected to the three phase conductors L1, L2 and L3 of a three-phase system. The rated voltage of the motor in the running connection must match the phase conductor voltages of the network.

When the three phases are operating in a time sequence and are connected to the terminals of the motor in alphabetical order U1, V1 and W1, clockwise rotation is established as viewed from the motor shaft. The direction of rotation of the motor can be reversed if two connecting leads are interchanged.

Labeled terminals are provided to connect the protective conductor.
A protective earth terminal is provided in the connection box for earthing. An earth terminal is located on the outside of the motor housing (special version in the case of 1LA5, 1LA6, 1LA7 and 1LA9 motors. Order codeL13).

If a brake control system or thermal protection is installed, the connections will also be in the connection box.
The motors are suitable for direct connection to the line supply.

Design of the connection box

Connection boxes for motors to (E)Exn (Zone 2) type of protection and for protection against dust explosions (Zone 21) differ from the basic version. For dust explosion protection (Zone 22), the connection boxes of the basic version are used.

For 1LG4 and 1LG6 motors, frame sizes 180 to 225 and 1MA6 motors frame sizes 180 to 200, 1MJ6 frame sizes 71 to 160 M and frame sizes 180 to 200 L, a connection box is available in cast iron.
Order codeK15
For 1LA6 and 1MA6 frame size 100 160, 1MJ6 frame size
160 L and 1MJ7, 1MA6 frame size 225 315 standard version.
Not possible for 1LA7 and 1MA7.

For 1MJ motors:
The connection boxes are designed to EEx e type of protection. The ends of the windings for motors up to frame size 160 are routed through a shared explosion-proof leadthrough into the connection box; for frame size 180 and above, they are routed through single leadthroughs.

For 1MJ motors, an explosion-proof connection box with
EEx d II C type of protection is available.

Fur die 1MJ-Motoren ist ein druckfester Anschlusskasten der Zundschutzart EEx d II C entspricht erhaltlich.
Order codeK53

For motor series 1LA8, 1PQ8 and 1LL8, the ends of the windings are routed through single leadthroughs into the connection box.

The number of terminals and the size of the connection box is designed for standard requirements. For special requirements or if the customer requires a larger connection box, the connection box for the next larger frame size can be supplied.

For all motors except for non-standard motors, 1MJ6 and 1MJ7 motors: Next larger connection box
Order codeL00

For non-standard motors (motor series 1LA8, 1PQ8 and 1LL8) Next larger 1XB1 621 connection box
Order codeM58 Next larger 1XB1 631 connection box
Order codeL00

Detailed assignment of connection boxes, see page 1/42.

If the necessary installation angle of the motor would cause machine components to collide with the connection box, the connection box can be moved from the drive end (DE) to the non-drive end (NDE). Order code M64 Not possible for explosion-proof motors.

Motor connection

Line feeder cables

The line feeder cables must be dimensioned acc. to DINVDE0298. The number of required feeder cables, if necessary in parallel, is defined by:

  • The max. cable cross-section which can be connected
  • The cable type
  • Routing
  • Ambient temperature and the corresponding maximum current in accordance with DINVDE0298

Cable entry on connection box

Unless stated otherwise, the cable entry is located in the standard position as shown in the illustration below.

The connection box can also be rotated such that the cable entry is located

  • Towards the drive end (DE) (rotation of connection box by 90, entry from DE)
    Order codeK83
  • Towards the non-drive end (NDE) (rotation of connection box by 90, entry from NDE)
    Order codeK84

With optionsK83andK84, 1LA7 motors of frame sizes 100 to 160 require an additional connection box upper section. This measure results in increased height of the connection box. The dimension AD increases by approx. 30mm, dimension AF changes depending on the frame size by between 45 and 47mm. For the precise values of AD and AF, see Dimension drawings in the corresponding sections of the catalogue.

If the cable entry is rotated by 180, special measures are required for 1LA7 and 1LA5 motors of frame sizes 63 to 90 as well as 180 to 225 (without a change in dimensions). (Rotation of the connection box by 180)
Order codeK85

From frame size 100 to 160, the break-outs in the connection box can be used.
The dimensions of the connection box are listed in the relevant sections of the catalogue in accordance with the frame size and the Dimension drawings.

If the position of the connection box (connection box RHS, LHS or above) is changed, the position of the cable entry must be checked and, if necessary, it can be ordered with the corresponding order codes (K83;K84;K85).

Ordering example

Connection box RHS (Order codeK09):
If no other order code is specified: Cable entry from below the motor.
With additional order codeK85:
Cable entry from drive end (DE)

For cable entry to a standard connection box, acable gland can be ordered for motor connection.
Cable entry, standard configuration
Order codeK54

For cable entry to a connection box with the options of motor protection or anti-condensation heating,two cable glands will be supplied.
Cable entry, maximum configuration
Order codeK55

For non-standard motors (motor series 1LA8, 1PQ8 and 1LL8), the cable entry can be implemented in accordance with DIN 89280 for the maximum possible configuration of cable entries in the connection box.
Order codeK57

A two-part plate on the connection box can be supplied if required.
Order codeK06

For special requirements for which the standard holes for the cable entries are inadequate, too large or when the routing must be implemented differently, an undrilled entry plate can be supplied to allow holes to be drilled as required on assembly.
Order codeL01

Protruding cable ends

With 1MJ motors, unused drilled holes must be sealed in accordance with
EN50014.

Terminal connection

The terminal board accomodates the terminals that are connected to the leads to the motor windings. The terminals are designed so that up to frame size 225, the external (line) connections can be made without the need for cable lugs. With frame size 250 and above, standard connection is with cable lugs.

For the 1LG4/1LG6/1LP4/1PP4 motor series, for frame sizes 250 to 315, stud terminals are available for connection using cable lugs (accessory pack, 3 items). Order codeM46

With frame size 250 and above, if connection without cable lugs is required, the appropriate saddle terminals for connection without cable lugs (accessory pack, 6 items) must be ordered. Order codeM47

For EExe and EExde motors, connection is generally without cable lugs.

The terminal board is permanently mounted on the housing for all motors so that if the connection box is rotated, rotation of the connections for the motor windings is prevented.
Exception:With connection boxes 1XB1 621 and 1XB1 631, the terminal support is mounted on the lower section of the connection box.

For motor series 1LA7/1LP7/1PP7 frame sizes 63 to 90, a terminal strip can be supplied for the main and auxiliary terminals.Order codeM69

The maximum number of auxiliary terminals in the main connection box of the motor is specified. An auxiliary connection box is required when the total number of auxiliary terminals exceeds the specified values. The connections can be routed through a separate auxiliary connection box.

For motor series

  • 1LA8, 1PQ8 and 1LL8 frame sizes 315 to 450
  • 1MA6 frame sizes 225 to 315

System ECOFAST

ECOFAST is a system which permits extensive decentralization and a modular structure for installation elements on the component level.

The following motor connectors are available for the separate MICROMASTER 411 frequency converter:

  • ECOFAST motor connector Han Drive 10e for 230VD/400VY
    Order code G55
  • ECOFAST motor connector EMC Han Drive 10e for 230VD/400VY
    Order code G56

In the basic version, cable entry for the ECOFAST connector
is towards the non-drive end (NDE). The dimensions of the ECOFAST motor connector depend on the motor frame size and can be read from the dimension drawing generator for motors in the SD configurator for low-voltage motors tool. It is particularly important to check the dimensions when a brake with a manual release lever is used towards the non-drive end (NDE) due to possible collision of the motor connector and manual release lever as well as in the direction of the drive end (DE) due to possible collision with drive units such as coupling or gear wheels.

Advantages:
The main advantages of the ECOFAST motor connector over a terminal strip are as follows:

  • Fast assembly of I/O devices (e.g. motor starters) from the ECOFAST system.
  • Reduction of assembly and repair times at the end user
  • No wiring errors due to connector technology
  • Replacement of motor without intervention in the electronics

Main features of the ECOFAST motor connector (with separate MICROMASTER 411 frequency converter):
The motor connector is mounted at the factory and replaces the connection box with terminal board. The connector is mounted towards the non-drive end (NDE). It comprises an angled motor connection casing that can be rotated by 4x90. A 10-pole
(+ earth) male insert is used in the housing. In the plug-in connector, the winding connections are connected and optionally the power supply for the brake and the signal leads for the temperature sensors. The ECOFAST motor connector is compatible with the products of the ECOFAST field device system. Further information can be found in Catalog IKPI.

The mounting dimensions of this casing match those of standard industrial connectors, so it is possible to use a complete series of different standard inserts (such as HanE, ES, ESS from Harting). The motor circuit (star or delta connection) is selected in the mating connector for motor connection. The relevant jumpers are inserted by the customer in the mating connector. As a casing for the mating connector, all standard sleeve casings with lengthwise locking, frame size 10B (e.g. from Harting) can be used.

Note:
Only one sensor (temperature sensor or PTC thermistor) can be connected. The maximum permissible line voltage at the motor connector is ?500V

Availability of the ECOFAST motor connector
The ECOFAST motor connector can be supplied for the following motor versions with the exception of the explosion-proof motors:

  • Frame sizes 56M to 132M
  • Output range 0.06 to 5.5kW (7.5kW on request)
  • Direct on-line starting: Voltage code 1 for 230VD/400VY, 50Hz
  • Star-delta starting: Voltage code 9 with order code L1U 400VD, 50Hz
