Description
This setpoint selects the range of the generator 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
The setpoint is used to adjust the mains voltage transformers ratio.
NOTE:
Adjust the setpoint to the value of 1.0 if the mains voltage is connected directly to
the controller terminals, i.e. without transformers.
NOTE:
Example: if you have transformers with ratio 6000/100V adjust the setpoint to the
value of 60.0.
NOTE:
The range of the mains voltage inputs must be adjusted properly. See the setpoint
Vm InpRangeSel.
