VOLTAGE SELECTOR SWITCH
The voltage selector switch is located under the control panel, next to the output connection lugs. The selector switch
is a three position switch that mechanically changes the connections between the generator output leads and the
connection lugs or optional cam lock connectors. Voltage ranges are selected by rotating the handle on the switch
to the desired voltage.
NEVER CHANGE THE VOLTAGE SELECTOR SWITCH WHILE THE ENGINE IS RUN-
NING!
This will cause severe arcing and damage to the switch and generator windings.
The connection lug door is equipped with safety interlock switches. If the door is opened while the unit is operating
the safety interlock switches will trip the main circuit breaker and disable the voltage regulator. The generator output
will drop down to residual voltage.
WARNING
Never attempt to disable or modify the lug door safety switches. Equipment damage,
personal injury or death may result.
Note: UNITS WITHOUT A CONVENIENCE OUTLET BUCK TRANSFORMER:
When the voltage selector switch
is in position for 480/277V 3Ø, voltage at the two GFCI duplex convenience outlets is 139 volts and the voltage at
the two twist-lock outlets is 240/139 volts. When the voltage selector switch is in position for 208/120V 3Ø, voltage
at the two twist-lock outlets and the two GFCI duplex convenience outlets is 208/120 volts.
