OUTPUT TERMINAL PANEL CONNECTIONS
UVWO TERMINAL OUTPUT VOLTAGES
Various output voltages can be obtained using the UVWO
output terminal lugs. The voltages at the terminals are
dependent on the placement of the jumper plates (6) on
the
Voltage Change-Over Board
and the adjustment of
the
Voltage Regulator Control Knob
.
Remember the voltage change-over board determines the
range
of the output voltage and can be configured in two
different positions that provide 6 different output voltages
at the UVWO output terminals. The generator is shipped
from the factory in the 240V configuration. The voltage
regulator (VR) allows the user to increase or decrease the
selected voltage.
3Ø-240V UVWO Terminal Output Voltages
1. Jumper the voltage change-over board for 240V
operation as shown in Figure 26.

2. Connect the load wires to the UVWO terminals as
shown in Figure 27.

3. Turn the voltage regulator knob (Figure 28) clockwise
to increase voltage output, turn counterclockwise to
decrease voltage output. Use the voltage regulator
adjustment knob whenever fine tuning of the output
voltage is required.

1Ø-240V UVWO Terminal Output Voltages
1. Make sure the voltage change-over board is jumpered
for 240V operation as shown in Figure 26.
2. Connect the load wires to the UVWO terminals as
shown in Figure 29.

1Ø-120V UVWO Terminal Output Voltages
1. Make sure the voltage change-over board is jumpered
for 240V operation as shown in Figure 26.
2. Adjust voltage regulator knob (Figure 28) for an output
of 208V to obtain 120V at the UVWO terminals.
3. Connect the load wires to the UVWO terminals as
shown in Figure 30.
