Generator AC Connection System
A single-phase, three-wire AC connection system is used in
the Home Generator System.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 wiring diagram
in Figure 10. A complete schematic and wiring diagram can
be found in the illustrated parts list manual.
NOTE: Neutral is not bonded to ground at generator.

INSTALLATION
Grounding the Generator
Ground the Home Generator System per applicable codes,
standards, and regulations.The generator GND lug is
located inside the control panel door under the circuit
breaker cover.
Utility Control Circuit Connection
Control circuit interconnections consist of "Utility" leads.
These two leads must be routed in conduit. Control lead
functions are briefly described as follows:
• "Utility 1" and "Utility 2" deliver utility power to the
generator's circuit board, optional battery warmer and oil
heater, charge the battery and when utility is lost the
generator will start.
Using installer-supplied minimum 300V, 14 AWG stranded
copper wire, connect each control circuit terminal in the
generator to the Automatic Transfer Switch.
Fault Detection System
The generator's control panel has a digital display to show
fault codes. It will display a fault code if certain faults are
detected in the HGS. An extra LED and mounting plate is
supplied so that it can be installed at a convenient indoor
location. It will turn on and off in a series of blinks if certain
faults are detected in the HGS.The owner will use it to
observe the status of the HGS. Consult with the owner for
a convenient location.
To install the remote LED panel:
• Push the LED through the mounting plate from the front
until it snaps in place.
• Using minimum 18 AWG wire, connect the remote LED
to the generator control board using supplied 10 pole
plug. Use wire nuts to attach wire to LED leads.
• Attach mounting plate to installer-supplied electrical box.
Refer to the section "Fault Detection System" in the
Operator's Manual for operation.
