5.3.3 Connection to Line Power and Grounding
NOTE!
The plug connector for power can be removed.
1. Make sure the adjustable frequency drive is properly grounded. Connect to ground connection (terminal 95). Use screw from the accessory bag.
2. Place plug connector 91, 92, 93 from the accessory bag onto the terminals labeled LINE at the bottom of the adjustable frequency drive.
3. Connect line power wires to the line plug connector.
The ground connection cable cross-section must be at least 0.016 in
2
[10 mm

] or have 2 rated line power supply wires terminated
separately according to EN 50178.
The AC line input connection is fitted to the line power supply switch, if one is included.
NOTE!
Make sure that the AC line voltage corresponds to the AC line voltage of the adjustable frequency drive nameplate.
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.
