9 Commissioning

The power supply unit is connected to the mains voltage via the IEC power connector and the mains switch.
The LED in the mains switch must light up after the unit is switched on. The blue LED on the unit for
indicating the operating status must light up.
Consumers should be connected while the power supply unit is switched off to prevent the possibility of
sparking.
The correct polarity must be noted: the red socket is the "24 V DC" connection, the blue socket is the "0 V"
connection. The output voltage is potential-free. The "0 V" connection must be connected to the earth
connection if the output voltage is to be referred to the reference potential of the supply network (earth
potential).
