Operating instructions
W2E250-HL06-19
Translation of the original operating instructions
For operation with variable frequency drives, install sinusoidal
filters that work on all poles (phase-phase and phase-ground)
between the drive and the motor.
During operation with variable frequency drives, an all-pole
sine filter protects the motor against high-voltage transients that
can destroy the coil insulation system, and against harmful
bearing currents.
Heating-up of the motor when using a variable frequency drive must be
checked by the customer following installation in the end device.
