2. Turn the controller pushbutton/rotary selector dial
until it stops at the Volt Select menu.

3. Press the selector dial and the voltage selection
option (second line on the display) will start to flash.
4. Turn the selector
counterclockwise

5. Press the selector dial. The second line on the
display will stop flashing and the new voltage will
appear.
6. Rotate the generator set voltage selector switch (if
equipped) to match the desired voltage shown on
the controller display. Skip steps 7--9 and go to
step 10.
If the generator set does not have a voltage
selection switch, continue to step 7
7. Disconnect the generator set engine starting
battery, negative (--) lead first. Disconnect power to
the battery charger (if equipped).
8. Use Figure 5-2, Figure 5-3, or Figure 5-5 to
determine the generator set voltage configuration.
Note the original voltage and reconnect as needed.
Route leads through current transformers (CTs)
and connect them according to the diagram for the
desired phase and voltage.
