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. A complete schematic and wiring diagram can be found on pages 26-27.

NOTE: Neutral is not bonded to ground at generator.

Remote Diagnostic LED Plate

The light on the remote LED plate is referred to as the Diagnostic LED.The LED will stay lit indicating the generator is in ready mode and will turn on and off in a series of blinks if certain faults are detected in the Home Standby Generator.A 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 Home Standby Generator. Consult with the owner for a convenient location.

To install the remote diagnostic LED plate:

•Mount installer-supplied electrical box to wall.

•Using installer-supplied wire, connect the remote LED leads to the “Remote Status Light” in disconnect box.

NOTE: LED leads are polarity sensitive.

• Attach mounting plate to electrical box.

Refer to the section “Fault Detection System” on page 20 for operation.

BEFORE INITIAL START-UP

Engine Oil

This engine is shipped from the factory filled with the recommended oil. Before starting the engine, check oil level and ensure that engine is serviced as described in the engine owner’s manual.

Grounding the Generator

Installer-supplied stranded copper wire is connected to the disconnect box GND lug and routed through conduit to the Transfer Switch GND. Continue the wire through conduit to the main distribution panel ground bus.

Generator Control Circuit

Connection

Control circuit interconnections consist of "240V AC Utility" leads.These two leads must be routed in conduit. Control lead functions are briefly described as follows:

•Leads deliver utility power to the generator’s circuit board, optional battery warmer and oil heater and charge the battery.

Using installer-supplied minimum 300V, 16 AWG stranded copper wire, connect control circuit terminals in the disconnect box to the Transfer Switch.

CAUTION

Any attempt to crank or start the engine before it has been properly serviced with the recommended oil will result in equipment failure.

•Refer to engine manual for oil fill information.

•Damage to equipment resulting from failure to follow this instruction will void warranty.

Oil Considerations

Your Home Standby Generator is equipped with an engine that has been pre-run at the factory and does not require the traditional “break-in” procedure.

The generator is filled with synthetic oil (API SJ/CF 5W- 30W).This allows for generator operation in the widest range of temperature and climate conditions.

NOTE: The use of synthetic oil DOES NOT alter the required oil change intervals described in the engine owner’s manual.
