The COMBIVERT G6-A corresponds to the drive converter 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 converters must have their own
starting current limiting at the DC voltage input.

ATTENTION
Unit switches off !
Cyclic switching on and off of the unit leads to temporary high resistance
of the resistor (PTC) in the input. The unit displays „Error! load shunt
fault“ in this state. When switching the control release during this fault,
the unit will switch off. A restart without limitation is possible after cooling.
Waiting time see „Technical data G6 400V class“.
4.2.1.1 Wiring instructions
ATTENTION
• Pay attention to the input voltage, 230 V and 400 V class are possi-
ble.
• Never exchange the mains and motor cables.
Some countries demand that the PE-terminal is directly connected to the termi-
nal box (not over the mounting plate).
