Description
This setpoint selects the range of the mains voltage terminals. The 120V range is
available only in IG-NTC and IS-NT. The IG-NT has the range adjusted fixedly to
277V regardless of this setpoint.
NOTE:
The 277V range is suitable for both European (230V) and American (277V)
measurement. The range 120V is intended for high-voltage applications where
voltage transformers with 100V secondary range are used or for alternative
American (120V) measurement.

Description
This setpoint is used to adjust the nominal (rated) generator voltage (phase to
neutral). If you do not know the phase-neutral nominal voltage, you can adjust the
phase-phase nominal voltage GenNomVph-ph. The controller will then recalculate
