4.2.3 Variable frequency drive
Please use a variable frequency drive only after consultation with ebm-
papst.
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.

sine filter protects the motor against high-voltage transients that
can destroy the coil insulation system, and against harmful
bearing currents.

checked by the customer following installation in the end device.
