Installation, Start-Up and Owner’s Manual

Generator AC Connection System

A single-phase, three-wire AC connection system is used in the 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.

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 stranded copper wire, connect control circuit terminals in the disconnect box to the Transfer Switch.

Remote 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 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 Standby Generator. Consult with the owner for a convenient location.

To install the remote 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.
