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.

3. Turn the voltage regulator knob (Figure 29) 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.
