2. Connect the load wires to the
as shown in Figure 28.
3. Turn the voltage regulator knob (Figure 24) clockwise
to increase voltage output, turn counterclockwise to
decrease voltage output.
1Ø-480V UVWO Terminal Output Voltages
1. Make sure the voltage change-over board is jumpered
for 480V operation as shown in Figure 27.
2. Connect the load wires to the
as shown in Figure 29.
3. Turn the voltage regulator knob (Figure 24) clockwise
to increase voltage output, turn counterclockwise to
decrease voltage output.

1. Jumper the voltage change-over board for 480V
operation as shown in Figure 27. This configuration uses
6 jumper plates in 3 different positions. Remember there
are 2 jumper plates at every position. Every jumper plate
must be used.

ALWAYS make sure that the
connections to the UWVO terminals
are secure and tight. The possibility
of arcing exists, which could cause
a fire
1Ø-277V UVWO Terminal Output Voltages
1. Make sure the voltage change-over board is jumpered
for 480V operation as shown in Figure 27.
2. Connect the load wires to the
as shown in Figure 30.
