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.

Three-Phase Position

2.Connect the load wires to the UVWO terminals as shown in Figure 22.

3Ø 208V/1Ø120V UVWO Terminal Output Voltages

1.Place the voltage selector switch in the 3Ø 240/139 position as shown in Figure 24.

Use this position for 3Ø-208 or 1Ø120V.

To achieve a 3Ø 208V output the voltage selector switch must

NOTEbe in the 3Ø-240/139 position and the voltage regulator must be adjusted to 208V.
