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 position of the Voltage Selector switch
and the adjustment of the Voltage Regulator control
knob.
Remember the Voltage Selector switch determines the
range of the output voltage. The voltage regulator (VR)
allows the user to increase or decrease the selected
voltage.

3. Turn the voltage regulator (Figure 18) clockwise
to increase voltage output, counterclockwise to
decrease voltage output. Use the voltage regulator
whenever fine tuning of the output voltage is required.

NOTICE
To achieve 3-phase 208-volt output, the Voltage
Selector switch must be in the 3-phase 240/139-volt
position and the voltage regulator must be adjusted to
208 volts.
