Control voltage is supplied by an external 24V power supply unit.
Note:
Technical data of control voltage: See page 6-10
The control voltage supply is connected via contact bars and screws (M6)
Design
at the front of the drive controller (cross section of a contact bar:
6 x 12 mm). Depending on the width of the drive controllers, there are
contact bars of different lengths.
6 Nm
By means of the DC bus connection, the following components are linked:
• the converter to other inverters
external additional capacitors are not allowed

If in special cases it is not possible to use the DC bus rails for connection,
connection must be established using the shortest possible twisted wires.
