VOLTAGE SELECTOR SWITCH
The voltage selector switch 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 running or the controller is
on. If the engine is running or starts while the setting is changed, severe arcing will occur
The voltage selector switch is equipped with a lockout mechanism. Once the proper voltage has been selected,
insert a padlock through the lockout hole(s). By locking the handle in place, unauthorized changing of the voltage
setting is prevented.
