3.3.5.1
Generator Voltage
General notes
The voltage measuring inputs for 120 V and 480 V are using the same terminals 30 to
36. The current voltage range must be selected by the corresponding settings via HMI
and/or ToolKit.
Parameter
("Gen. PT secondary rated volt.") must be configured to the correct
value to ensure proper measurement.

Parameter Setting '3Ph 4W OD' (3-phase, 4-wire, Open delta)
Generator windings
A generator system that is connected to the load through a 3-phase, 4-wire connection
but have the device wired for a 3-phase, 3-wire installation may have the L2 phase
grounded on the secondary side. In this application the device will be configured for 3-
phase, 4-wire OD for correct power measurement.
