IT Line Power
Do not connect 400 V adjustable frequency drives with RFI filters to line supplies with a voltage between phase and ground of more
than 440 V.
For IT line power and delta ground (grounded leg), AC line voltage may exceed 440 V between phase and ground.
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.
