Note: Do not connect C3 filters in IT power systems.
Interference filters on the input side can reduce the VFD interference on the surrounding devices.
Noise filters on the output side can decrease the radio noise caused by the cables between VFDs and
motors and the leakage current of conducting wires.
INVT provides some of the filters for you to choose.
