Generator AC Connection System
A single-phase, three-wire AC connection system is used in
this generator. The stator assembly consists of a pair of
stationary windings with two leads brought out of each
winding. The junction of leads 22 and 33 forms the neutral
lead, as shown schematically and as a wiring diagram. A
complete schematic and wiring diagram can be found in
Section 4 - Generator Specifications.
NOTICE: Neutral is not bonded to ground at generator.
Automatic Operation
To select automatic operation, proceed as follows:
1. Confirm 15 Amp fuse is installed.
2. Turn on the main distribution panel circuit breaker
that sends utility voltage to the transfer switch.
3. Turn on the generator circuit breaker.
4. Set the control panel system switch to AUTO .
Checking Automatic Operation
To check the system for proper automatic operation, proceed
as follows:
1. Turn OFF the circuit breaker that sends utility power
to the automatic transfer switch.
NOTICE: When utility voltage is lost and the sensor has timed
out, the engine will crank and start. Let the system go
through its entire automatic operation sequence.
2. With the generator output supplying power, turn ON
the circuit breaker that supplies utility power to the
automatic transfer switch.
3. The automatic transfer switch will transfer loads back
to utility power after a 5 minute minimum run time.
4. The generator will run for an additional one minute
for engine cool down, then shut down.
If utility is restored and generator does not shut down after
10 minutes, set control panel system switch to
OFF and
proceed to Section 2 - Troubleshooting.
CAUTION With the system switch set to AUTO, the
engine may crank and start at any time without
warning.
• To prevent possible injury that may be caused by
sudden starts, always set the system switch to OFF if
performing maintenance on the system.
• Remove the 15 Amp fuse before working on or
around the generator or transfer switch.
