24 V DC power supply

24 V DC power supply, installed
The optional 24 V DC power supply enables the internal elec-
tronics to be supplied with 24 V DC directly from the DC link.
No external cable is needed for the 24 V DC supply and only
the 400 V 3 AC line supply has to be connected. The optional
24 V DC power supply supplies power to the internal circuitry of
the Control Unit, the low-voltage circuits of the Power Module
and all inputs and outputs.
Note:
It is possible to install either a 24 V DC power supply or a repair
switch, but it is not possible to install both options on the same
unit.
