INSTALLATION

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.
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 Circuit Connection
"240V Utility" leads must be routed in conduit. Functions are
briefly described as follows:
• "240V Utility" delivers power to the generator’s circuit
board, optional battery and oil warmer, charge the battery
and when utility is lost the generator will start.
Using provided 2 pole connector and installer-supplied
minimum 300V, 14 AWG 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 provided 10 pole connector and installer-supplied
minimum 18 AWG wire, connect the remote LED to the
generator control board. Use wire nuts to attach wire to
LED leads.
IMPORTANT: The LED is polarity sensitive.
• Attach mounting plate to installer-supplied electrical box.
Refer to the section “Fault Detection System” in the
Operator’s Manual for operation.
