Description
The setpoint is used to adjust the busL voltage transformers ratio.
NOTE:
Adjust the setpoint to the value of 1.00 if the busL 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 60.00.
NOTE:
The range of the busL voltage inputs must be adjusted properly. See the
setpoint VbL InpRangeSel.

Description
This setpoint selects the range of the busL voltage terminals. The 120V
range is available only in IM-NTC hardware. The IM-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.
