Caution
Large EMC faults can occur as a result of three-phase motors being opera-
ted when connected in star formation (particularly when < 1 kW).
Faults above the IEC limit values can lead to impairment of function or fai-
lure of the electronics.
We recommend using motors featuring EMC protective circuits in the case
of high EMC faults. (Exception: Electronic starters must not be operated
with an EMC protective circuit). The best filter effect is achieved using
3-phase RC interference suppression modules. Varistor interference sup-
pression modules should not be used, as these do not filter out rapid transi-
ents to a sufficient extent.
