Safety guideline
The following applications are illustrated merely as examples of circuits.
No liability is accepted for the functionability, certifiability or compatibility of the
examples. Use at your own risk.
Caution
The operation of 3-phase motors in a star-shaped circuit can lead to high EMC
interference (especially if < 1 kW). Interference exceeding the IEC limits values
can lead to functional impairments or failure of the electronics. In the event of
high EMC interference, we recommend using motors with EMC protective cir-
cuits. (Exception: electronic starters may not be operated with an EMC protec-
tive circuit).
The best filter effect is achieved with 3-phase RC screening modules.
Varistor screening modules should not be used, as these only inadequately filter
our rapid transients.
