UVWO Terminal Output Voltages
Various output voltages can be obtained using the using the
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.
3Ø 240/139 Output Terminal Lug Voltages
1. Place the voltage selector switch in the 3Ø 240/139
position as shown in Figure 21.

Three-Phase Position
2. Connect the load wires to the Output Terminal Lugs as
shown in Figure 22.

3. Turn the voltage regulator knob (Figure 23) clockwise to
increase voltage output, turn counterclockwise to
decrease voltage output.

3Ø 208V/1Ø120V Output Terminal Lug Voltages
1. Place the voltage selector switch in the 3Ø 240/139
position as shown in Figure 24.
2. Connect the load wires to the Output Terminal Lugs as
shown in Figure 25.

3. Turn the voltage regulator knob (Figure 23) clockwise to
increase voltage output, turn counterclockwise to
decrease voltage output.
NOTE
Use this position for
3Ø-208 or 1Ø120V.

Three-Phase Position
To achieve a 3Ø 208V output,
the voltage selector switch
must be in the 3Ø 240/139V
position and the voltage
regulator must be adjusted to
208V.
