24 V DC power supply

24 V DC power supply, installed

The optional 24 V DC power supply enables the internal electronics 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:

Either a 24 V DC power supply or a repair switch can be installed .
The simultaneous use of both options is not possible.
