UVWO Output Voltage Change-Over Board
Terminal Lugs 3-Phase 240/139V Position
3Ø Line-Line 208V
1Ø Line-Neutral 120V
VOLTAGE CHANGE-OVER BOARD
Voltages are selected by applying six jumpers to the
voltage change-over board (Figure 17), which is located
on the control box behind the generator control panel. This
board is provided for ease of voltage selection.

WARNING
NEVER attempt to place jumper plates on the voltage
change-over board while the generator is in operation.
There exists the possibility of electrocution, electrical
shock, or burn, which can cause severe bodily harm
or even death!

VOLTAGE REGULATOR
To obtain some of the voltages listed in Table 8 will require
a fine voltage adjustment using the voltage regulator
(Figure 18) located on the control panel.
