5.2.2.3

Use of the K82 option with Control Unit CU320-2

If option K90 or K95 is not available, -X41:10 should be connected to the particular Control
Unit associated with the Motor Module. Digital inputs DI 0 to DI 7, DI 16, DI 17, DI 20, DI 21
are available for this purpose.
These interconnections have to be taken into account when Safety function parameters are
assigned.
If the cable is routed to the Control Unit outside the cabinet, then the cable may not be
longer than 30 m. For longer cable lengths, suitable protective circuitry must be provided for
overvoltage protection (Weidmüller, type: MCZ OVP TAZ, order no.: 8449160000).
Note
Terminal -X41:10 can only be connected with digital inputs DI 0 to DI 7, DI 16, DI 17, DI 20,
DI 21 of the Control Unit, other digital inputs cannot be interconnected.
5.2.2.4

Wiring

The control cables should be permanently routed (e.g. cable duct, retained using cable ties).
Signal cables and encoder cables should be installed separated from one another.
The shields of the control cables should be grounded through the largest possible surface
area immediately after they enter the control cabinet.
Outside the control cabinet, the cables must be routed in such a way that they are safe to
walk on (e.g. as specified in IEC 60204-1).
5.2.3

Terminal module for control of "STO" and "SS1" for SINAMICS S150

Description
Option K82 (Terminal Module for activating "Safe Torque Off" and "Safe Stop 1") is used for
isolated activation of the Safety Integrated Basic Functions over a wide voltage range.
Note
Refer to the circuit diagrams enclosed for the interconnections of your device.
Note
The Safety functions must be activated prior to use via parameter assignment. An
acceptance test must be performed and an acceptance log must be created.
