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. A complete schematic and wiring diagram can be found on pages 24-25.

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 stud is located inside the control panel door, behind control panel.

Generator Control Circuit

Connection

Control circuit interconnections consist of "240V AC Utility" leads.These two leads must be routed in minimum 3/4” conduit. Control lead functions are briefly described as follows:

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

Remote Start Switch with LED

The light on the remote start switch plate is referred to as the LED.The LED will light indicating the generator has started when pushing the start switch. 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 Generator System. Consult with the owner for a convenient location.

To install the remote start switch plate:

•Mount installer-supplied electrical box to wall.

•Using installer-supplied wire, connect the remote start switch and the “Remote Status Light” leads to the control panel terminal strip.

NOTE: LED leads are polarity sensitive.

• Attach mounting plate to electrical box.

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 operator’s manual.

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 Generator System 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 operator’s manual.
