Analog inputs that are not
used are to be connected to
ground reference!
To avoid undefined conditions at external supply, the supply should always be switched
on first and then the inverter. In the delivered state the inputs are controlled with a posi-
tive voltage (PNP). This can be effected through an external supply as well as the internal
supply:
