4.2.1 Connection of the voltage supply
The COMBIVERT G6-C corresponds to the drive controller type A1. This type can be
supplied both by mains and via DC terminals. The starting current limiting is arranged
before the DC link. When using as DC output parallel connected drive controllers must
have their own starting current limiting at the DC voltage input.
