1.1 Product Description
In selecting the KEB COMBIVERT you have chosen a frequency inverter with the
highest demands for quality and dynamic.
It exclusively serves for a stepless speed regulation of the three-
phase motor.
The operation of other electrical loads is forbidden an can lead to
disturbances of the unit.
This manual describes the control of the standard series

KEB COMBIVERT is conditionally short-circuit proof (VDE 0160). After the internal
protector is reset the normal function is guaranteed.
Exceptions: If an earth-leakage fault or short-circuit proof often occur, this can
lead to a defect in the unit.
If a short-circuit occurs during regenerative operation (2nd or 4th
quadrant, feedback into the intermediate circuit), then this can lead
to a defect in the unit.
1.2 Safety Instructions
The KEB COMBIVERT is operated with voltage, which can cause an extremely
dangerous shock when come into contact with. Therefore the installation of the unit
and accessories is only permissible by qualified electro-personnel. A safe and trouble-
free operation is only possible when the valid regulations according to DIN VDE 0100,
IEC1000, EN 60204-1, EN 55014, EN 50082-2 and the relevant regulations for your
area are observed.
After clearing the frequency inverter the intermediate circuit capacitors are still charged
with high voltage for a short period of time. The unit can be worked on again after it
has been switched off for 5 minutes.
KEB COMBIVERT is adjusted so that after a voltage breakdown or an UP-error it can
restart alone. The machine manufacturer is responsible for the corresponding safety
precautions.
