IT Line
Do not connect 400 V adjustable frequency drives with RFI filters to the line supply with a
voltage between phase and ground of more than 440 V.
For IT lines and delta ground (grounded leg), line voltage may exceed 440 V between phase
and ground.
On the FC 302, par. 14-50
RFI 1
can be used to disconnect the internal RFI capacitors from the RFI filter
to ground. If this is done, it will reduce the RFI performance to A2 level.
