Installation Manual

Generator AC Connection System

A single-phase, three-wire AC connection system is used in the Home Standby 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 wiring diagram in Figure 10. A complete schematic and wiring diagram can be found in the operator’s manual.

NOTE: Neutral is not bonded to ground at generator.

Grounding the Generator

Ground the Home Standby Generator per applicable codes, standards, and regulations.The generator GND lug is located inside the air intake door.

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, charge the battery and when utility is lost the generator will start.

Using 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 light on the control panel is referred to as the Diagnostic LED. It will turn on and off in a series of blinks if certain faults are detected in the HSG. An extra LED and mounting plate is supplied so that it can be installed at a convenient indoor location.The owner will use it to observe the status of the HSG. Consult with the owner for a convienant location.

To install the remote LED panel:

Apply the supplied decal to the supplied mounting plate.

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 pin connectors. 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.
