4.1.3 Grounding and IT line power
The ground connection cable cross-section must be at least 0.016 in
according to
EN 50178 or IEC 61800-5-1
tions on cable cross-sections.
The line power is connected to the main disconnect switch if this is included.
NOTE!
Make sure that the AC line voltage corresponds to the AC line voltage of the adjustable frequency drive nameplate.
Figure 4.1: Terminals for line power and grounding.
IT Line Power
Do not connect 400 V adjustable frequency drives with RFI filters to line power 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.
