9-2. 208/240/480V Switching Selection
WARNING : ELECTRIC SHOCK
If performing any electric voltage switching, turn all breakers to OFF and stop
operation.
Lock the generator using a padlock so that no one except for designated operators
can operate switches.
CAUTION : PROPERTY DAMAGE
Check that the voltages of the generator output setting, output terminal connection
and load power source are consistent.
Turn the three-phase and single-phase breakers on the operation panel to OFF and press
1
Power Switch to turn off the main power and stop the engine.
Turn the lever of the voltage (208/240/480 V) selector switch to the desired output setting.

When you start the engine, the set voltage is output from the output terminal. Refer to
3
section "9-1. Starting/Stopping Operation".
Three-Phase
208/120V
< Note >
When using the three-phase 480V setting, the available output of the single-phase three-wire
system becomes half compared to the three-phase 208/240V setting, be careful not to
overload.
The output voltage of the single-phase 3-wire type is always 240/120V.
