Controlling the safety functions
5.2 Control of "STO" and "SS1" via terminal module for option K82
Note
Terminal -X41:10 is permanently connected to the digital input DI 7 of the Control Unit.
Note
For the following cabinet units (parallel switchgear), digital input DI 6 of the Control Unit is
also assigned:
• For 380 to 480 V 3 AC:
6SL3710-2GE41-1AAx, 6SL3710-2GE41-4AAx, 6SL3710-2GE41-6AAx
• For 500 to 600 V 3 AC:
6SL3710-2GF38-6AAx, 6SL3710-2GF41-1AAx, 6SL3710-2GF41-4AAx
• For 660 to 690 V 3 AC:
6SL3710-2GH41-1AAx, 6SL3710-2GH41-4AAx, 6SL3710-2GH41-5AAx
Interconnection in groups
When using a single actuating element for multiple cabinet units, the following terminals
have to be used on terminal strip -X41:
● -X41:2: Interconnection to the next cabinet unit, terminal -X41:1
● -X41:4: Interconnection to the next cabinet unit, terminal -X41:3
● -X41:6: Interconnection to the next cabinet unit, terminal -X41:5
● -X41:8: Interconnection to the next cabinet unit, terminal -X41:7
● -X41:9: Interconnection to the next cabinet unit, terminal -X41:6
● Connection of the optional checkback signal to terminal -X41:9
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).
