3.2 Operation with rated power (normal operation)
The data applies to operation with rated mains voltage and a switching frequency of 8 kHz
(sine). For data and restrictions for other switching frequencies: See operating
instructions.

The output currents apply to operation with fan module E82ZMV or with forced−ventilated Lenze motors/geared motors.
For the operation with self−ventilated Lenze motors/geared motors, the rated output current must be reduced (see
