The value is always entered as the “Phase - phase” measure-
ment. Some applications may require the use of potential trans-
formers to facilitate measuring the busbar voltages. The rating of
the secondary side of the potential transformer must be entered
into this parameter. If the application does not require potential
transformers (i.e. the measured voltage is 480 V or less), then the
measured voltage will be entered into this parameter.
• Rated voltage: 120 Vac (this parameter configured be-
tween 50 and 130 V)
o Busbar voltage: Terminals 37/39
o Auxiliary busbar voltage: Terminals
21/23/25/27
• Rated voltage: 480 Vac (this parameter configured be-
tween 131 and 480 V)
o Busbar voltage: Terminals 38/40
o Auxiliary busbar voltage: Terminals
22/24/26/28
NOTE: The control is equipped with dual voltage measuring in-
puts. The voltage range of these measurement inputs is depen-
dent upon what terminals are used. This value refers to the sec-
ondary voltages of the potential transformers, which are directly
connected to the control.
WARNING: Only connect the measured voltage to either the
120 Vac or the 480 Vac inputs.

Operating Ranges
NOTE
The operating ranges are settings, which are used for determining the generator is operating at the
correct voltage and frequency. Drop out of the operating range is not monitored with an alarm. The op-
erating ranges are valid for generator, busbar and auxiliary busbar measurement, if used. It is recom-
mended to configure the operating limits within the monitoring limits.
NOTE
For monitoring the operating ranges respectively, the information can be read by interface or the Home
page in ToolKit and is also displayed by the LEDs conditions.
