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
• -X41:8: Interconnection to the next cabinet unit, terminal -X41:7
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).
