11.2 Before switching on
Prior to supply voltage connection, check
z
the wiring for completeness, earth faults and short circuits
z
the system bus wiring (CAN)
– The first and last node must be connected to a 120 Ω resistor.
z
spatial cable separation from signalling and mains cables.
Note!
After switching on the supply voltage, the modules of the I/O
system IP20 are initialised. During the initialisation, the modules
cannot be parameterised.
z
Initialisation time - modular system: approx. 10 s
z
Initialisation time - compact system: approx. 1 s
