Interconnection in groups
When using a single activation 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 lines must be permanently laid.
Signal cables and encoder cables should be installed separated from one another.
The shields of the control lines must be wide-area grounded directly after entry into the
control cabinet.
Outside the control cabinet the cables must be laid in such a way that they are safe to walk
on (e.g. as specified in IEC 60204-1).
