3.2.1.1 Wiring instructions
Never exchange the mains and motor cables.
Some countries demand that the PE-terminal is directly connected to the terminal box
(not over the mounting plate).
All work from the transport, to installation and start-up as well as mainte-
nance may only be done by qualified personnel (IEC 364 and/or CENELEC
HD 384 and IEC-Report 664 and note national safety regulations). Accor-
ding to this manual qualified staff means those who are able to recognise
and judge the possible dangers based on their technical training and ex-
perience and those with knowledge of the relevant standards and who are
familiar with the field of power transmission.
KEB COMBIVERT units contain dangerous voltages which can cause death
or serious injury.
The KEB COMBIVERT can be adjusted in such a way that energy regene-
ration into the supply net is possible at regenerative operation also during
mains power failure. Therefore a dangerous high tension can exist in the
unit after switching off the supply system.
Before working with the unit check the isolation from supply by mea-
surements in the unit. Motors are to be secured against automatic
starting.
Care should be taken to ensure correct and safe operation to minimise risk
to personnel and equipment.
The COMBIVERT G6-C corresponds to the inverter 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
+
frequency inverters must have their own starting current
limiting at the DC voltage input..
