Prior to supply voltage connection, check
l the wiring for completeness, short circuits and earth faults
l the wiring of the fieldbus
– A bus terminating resistor has to be connected to the first and the last
node.
l spatial cable separation from signalling and mains cables.

Note!
After connecting the supply voltage, the modules of the I/O
system IP20 are initialised. During the initialisation, the modules
cannot be parameterised.
l Initialisation time: approx. 10 s
