4-POSITION VOLTAGE SELECTOR SWITCH OPTION
The optional four position voltage selector switch is located on a panel attached to the generator behind the door
located next to the fuel tank filler. The voltage selector is a four position switch that mechanically changes the
connections between the generator output leads and the connection lugs on the main control panel. 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 voltage selector switch is equipped with a locking mechanism. Once the proper voltage has been selected, push
the red latch on the inside of the switch handle up and insert a padlock through the handle. By locking the handle in
place, you will prevent unauthorized personnel from changing the switch settings.
Note:
UNITS WITHOUT A CONVENIENCE OUTLET BUCK TRANSFORMER: When the voltage selector switch is
in position for 277/480V 3Ø, voltage at the two GFCI duplex convenience outlets is 139 volts and the voltage at the
three twist-lock outlets is 139/240 volts. When the voltage selector switch is in position for 120/208V 3Ø, voltage at
the two GFCI duplex convenience outlets is 120 volts and the voltage at the three twist-lock outlets is 120/208 volts.
When the voltage selector switch is in position for 120/240 3Ø (DELTA), voltage at the two GFCI duplex convenience
outlets is 120 volts and the
THREE 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 three twist-lock outlets is 120/240 volts.
Convenience outlets should not be used in the 480/277 voltage setting as the voltage will
be higher and equipment damage could result.
