Configuration
2. Connect the load wires to the UVWO terminals as shown in Figure 19.

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 placement of the jumpers plates (6) on the Voltage Change-Over Board and the adjustment of the Voltage Regulator Control Knob.
Remember the voltage change-over board determines the range of the output voltage and can be configured in two different positions that provide 6 different output voltages at the UVWO output terminals. The generator is shipped from the factory in the 240V configuration. The voltage regulator (VR) allows the user to increase or decrease the selected voltage.

3. Turn the voltage regulator knob (Figure 20) clockwise to increase voltage output, turn counterclockwise to decrease voltage output. Use voltage regulator adjustment knob whenever fine tuning of the output voltage is required

1. Make sure the voltage change-over board is jumpered for 240V operation as shown in Figure 18.
2. Adjust voltage regulator knob (Figure 20) for an output of 208V to obtain 120V at the UVWO terminals.
3. Connect the load wires to the UVWO terminals as shown in Figure 22.
