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 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 confi gured 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 confi guration. The voltage regulator (VR) allows the user to increase or decrease the selected voltage.
3Ø-240V UVWO Terminal Output Voltages
1. Jumper the voltage change-over board for 240V operation as shown in Figure 18.
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 fi ne tuning of the output voltage is required
