9.3.2 Derating and Mains Voltage
Reduced over current capability based on mains voltage
The Fv frequency converters are thermally dimensioned for the rated cur‐
rents. This rated current is available with the specified rated voltage. With de‐
viating voltages in the permissible range, please note the following:
● U
mains
< U
rated
: With mains voltages below the rated voltage, no higher
currents may be withdrawn to keep the same dissipated power.
● U
mains
> U
rated
: With mains voltages greater than the rated voltage, a re‐
duction of the continuous output current in the permissible range takes
place to compensate for the increased switching losses.

At mains voltage < 380 V: 1 % power derating every 4 V.
