VOLTAGE SELECTOR SWITCH
The voltage selector switch is located on a panel attached to the generator behind the door located next to
the fuel tank filler. The selector switch is a three position switch that mechanically changes the connec-
tions 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.
The voltage switch is equipped with a locking mechanism. Once the proper voltage has been selected,
push the red latch on the inside of the phase 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: When the voltage selector switch is in position for 480/277V 3O, voltage at the two GFCI duplex
convenience outlets is 139 Volts and the voltage at the three twist-lock outlets is 240/139 Volts. When the
voltage selector switch is in position for 208/120V 3O, voltage at the three twist-lock outlets and the two
GFCI outlets is 208/120 volts.
