4.2.3 Frequency inverter
Please use a frequency converter only after consultation with ebm-papst.
For operation with frequency converters, fit sinusoidal filters that
work on all poles (phase-phase and phase-earth) between the
frequency converter and the motor.
During operation with frequency converters, an all-pole sine
filter protects the motor against high-voltage transients that can
destroy the winding insulation system, and against harmful
bearing currents.
Heating-up of the motor when using a frequency converter must be
checked by the customer following installation in the end device.
