4-POSITION VOLTAGE SELECTOR SWITCH OPTION
The voltage selector switch is located under the control panel, next to the connection lugs. This optional selector
switch is a four position switch that mechanically changes the connection 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 convenience outlets is 240/139 volts. When the voltage selector switch is in position for 208/120V
3Ø, voltage at the two GFCI duplex convenience outlets is 120 volts, and the voltage at the two twist-lock convenience
outlets is 208/120 volts. When the voltage selector switch is in position for 120/240V 3Ø (DELTA), voltage at the two
GFCI duplex convenience outlets is 120 Volts, and the
TWO TWIST-LOCK OUTLETS SHOULD NOT BE USED
.
When the voltage selector switch is in position for 120/240V 1Ø, voltage at the two GFCI duplex convenience outlets
is 120 volts, and the voltage at the two twist-lock outlets is 120/240 volts.
