●  -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).
