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 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.

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

NOTICE
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.
