Output Terminal Panel Connections - MQ Power WHISPERWATT Series Operation Manual

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 jumper plates (6) on
the voltage change-over board.
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 240-volt configuration.
3-Phase 240-Volt UVWO Terminal Output Voltages
1. Jumper the voltage change-over board for 240-volt
operation as shown in Figure 14.

1. Make sure the voltage change-over board is jumpered
for 240-volt operation as shown in Figure 14.
2. Select an output of 208 volts on the digital controller
to obtain 120 volts at the UVWO terminals.
3. Connect the load wires to the UVWO terminals as
shown in Figure 17.

NOTICE
BE USED
To obtain single-phase, 120-volt output, the voltage
change-over board must be in the 3-phase, 240/139-volt
position and the voltage on the digital controller must
be set to 208 volts.
