OPERATIONAL TESTING

1. Switch the generator's main circuit breaker OFF and put the
mode switch in the OFF position.
2. Make sure utility power is OFF and place all of the priority
circuit breakers in the transfer switch in the OFF position.
3. Locate the transfer handle, insert the metal end into the slot
in the main contactor assembly and pull the handle DOWN to
move the main contacts to the standby power, or generator
position.
NEVER OPERATE THE TRANSFER SWITCH
MANUALLY WHEN LOADS ARE CONNECTED.
4. Put the generator's mode switch in MANUAL to start the engine.
Allow the engine to warm up, then switch the generator's
main breaker to the ON position. The generator is now
supplying electricity to the transfer switch but is not carrying
any load.
5. Be sure that voltage and frequency from the generator is
correct. If line-to-line voltage is not approximately 240
volts, refer to the Owner's Manual for the proper adjustment
procedures. On all models, if line-to-neutral voltage is not 120
volts, check the neutral connection between the generator and
transfer switch.
6. When finished checking the voltage, switch the generator's
main circuit breaker OFF and put the mode switch in the OFF
position to shut down the generator.
7. Make sure the 2-pole circuit breaker installed in the main
distribution panel is in the OFF position.
