DCA-70SSJU SERIES — 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 de-
pendent 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 UVWO Terminal Output Voltages
1. Place the voltage selector switch in the 3Ø 240/139
position as shown in Figure 21.

2. Connect the load wires to the UVWO terminals 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 UVWO Terminal Output Voltages
1. Place the voltage selector switch in the 3Ø 240/139
position as shown in Figure 24.
Figure 23. Voltage Regulator Knob (139V/240V)
Use this position for
3Ø-208 or 1Ø120V.
2. Connect the load wires to the UVWO terminals as shown
in Figure 25.
3. Turn the voltage regulator knob (Figure 26) clockwise to
increase voltage output, turn counterclockwise to
decrease voltage output.

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