3.3.8.2 Auxiliary power supply 400V 3 AC 50Hz
The following components require an auxiliary power supply of 3AC 400 V:
● Fan
● Open-loop and closed-loop control
● Protection and monitoring equipment
● DC link precharging
Refer to the drive technical data for auxiliary power supply current rating. The terminal
assignment is provided in the circuit diagram of the drive.
3.3.9 Customer terminal strips
The signals are allocated to various terminal strips according to voltage level. The cables are
visually distinguished from one another by various colors. Barriers mechanically separate
cables carrying different potentials on one terminal strip. The terminals are suitable for cables
with a cross-section of 2.5 mm
