2. Terminal Block Hertz/AC Voltage Connections
To make the desired hertz and AC voltage change, properly connect the AC terminal connection to the
generator's terminal block (see the illustration below). Note the positioning of the copper connectors
between terminals as well as the repositioning of the white or white with green stripe ground wire from
the neutral bar to generator case ground. Failure to do so will result in damage to the main stator windings.

Start the generator and check the hertz and voltage being produced. Adjust the governor as needed
for correct no-load hertz.
No-Load Voltage Adjustment
If the generator was producing the correct no-load voltage before the hertz change, this adjustment
may not be necessary. In the event a no-load adjustment is needed, proceed as follows.
A. Shut off the generator.
IWARNINGI
Do not attempt to make a no-load voltage adjustment while the generator is operating. The
capacitor can hold a 450 - 500 volt charge. Touching any wiring can result in a severe electrical
shock. In addition, attempting to make a no-load voltage adjustment while the generator is
operating can cause fingers to be caught in the generator's rotor.
B. Refer to the illustrations on the previous page before making any adjustments. Note that there are three
plugs grouped for the right capacitor terminal, #7, #8, and #9. If the generator's no-load voltage is
low, then disconnect the lower number plug and connect the plug with the' next higher number. If the
generator's no-load voltage is high, then disconnect the higher numbered plug and connect the plug
with the next lower number. Note that the plug presently connected to this terminal may be anyone of
the three plugs available.
NOTE: Voltage variation between each plug is approximately 8 - 10 volts AC.
