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 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.
