For most applications, this manual contains the information necessary for the correct installation, operation, and maintenance of the equipment. All efforts have been made to make sure that the information in this manual is accurate and current. We reserve the right to change the product and this document without notification. Equipment Description NOTICE This product does NOT qualify for either an emergency standby or legally required standby system as defined by NFPA 70 (NEC).
Generator Placement Before installing the generator, consult with the owner and convey the following requirements, which must be satisfied before the installation is complete. There are two equally important safety concerns in regards to carbon monoxide poisoning and fire. There are also several general location guidelines that must be met before the installation is considered complete. WARNING (A) Exhaust outlet side of enclosure.
n N o R tf ep o r ro du ct io All fossil fuel burning equipment, such as standby generators (A), contains carbon monoxide (CO) gas in the engine exhaust (H). CO gas is odorless, colorless and tasteless and is unlikely to be noticed until a person is overcome. CO gas can kill you so it is required that the following is included as part of the installation. • Install generator (A) outdoors in an area that will not accumulate deadly exhaust gas (H).
n N o R tf ep o r ro du ct io • Nearby structures may be exposed to the engine exhaust (H) from the generator (A) and must be considered when installing the standby generator. • Wind and air currents should be taken into consideration when positioning the generator (A). Place the generator in an area where winds will carry the exhaust gas (H) away from any potentially occupied building or structure. • DO NOT place the standby generator (A) in any area where leaves or debris can accumulate.
n N o R tf ep o r ro du ct io Legend for Generator Locations to reduce the risk of fire: (A) Standby Generator 12
(B) Standby enclosure must be at least 5 ft (1.5 m) from windows, doors, any wall opening, shrubs or vegetation over 12 inches (30.5 cm) in height. (C) Exhaust outlet of standby enclosure must have at least 5 ft (1.5 m) minimum clearance from any structure, shrubs, trees or any kind of vegetation. (D) Standby enclosure must have a minimum of 5 feet (1.5 m) overhead clearance from any structure, overhang or trees. (E) Standby enclosure must have a minimum of 18 inches (45.
Installation This product is only for use as an optional generator system which provides an alternate source of electric power and to serve loads such as heating, refrigeration, and communication systems that, when stopped during any power outage, can cause discomfort or inconvenience. Every effort has been made to make sure that the information in this manual is accurate and current.

Electrical Field Connections WARNING Generator and utility voltage could cause electrical shock or burn resulting in death or serious injury. • Installation must be performed by a licensed professional. • Disconnect all sources of electricity before installing or servicing equipment. • Ground system before applying power. WARNING Hazardous Voltage - Installing low and high voltage wire in same conduit could cause electric shock or burns, resulting in death or serious injury.
(H) Neutral Connection — Connect to transfer switch neutral wire. (J) Communications Terminal Block — Reference the table that follows. Pin Number Description Wire type Connect To 2 1 12VDC 18AWG[1mm ] conductors, Transfer switch basic 300V minimum, 90°C Cu wire. controller J7-8 12VDC 2 GND 18AWG[1mm ] conductors, Transfer switch basic 300V minimum, 90°C Cu wire. controller J7-7 GND 3 Transfer Signal 18AWG[1mm ] conductors, Transfer switch basic 300V minimum, 90°C Cu wire.
240V Utility leads must be routed in conduit. The 240V Utility leads deliver power to the generator’s circuit board, optional battery warmer and optional oil warmer. This power also charges the battery. In AUTO Mode, when the power on these leads is lost, the generator will start. Using the installersupplied minimum 300V, 14 [2.5 mm2] AWG wire, connect each control circuit terminal in the generator (25 and 26) to the fuse block in the automatic transfer switch.
Generator and utility voltage could cause electrical shock or burn resulting in death or serious injury. • Installation must be performed by a licensed professional. • Disconnect all sources of electricity before installing or servicing equipment. • Ground system before applying power. WARNING Battery electrolyte fluid contains acid and is extremely caustic. Contact with battery contents could cause severe chemical burns. Use the supplied tie-down strap to secure the battery to the unit.
Initial Start-Up (No Load) WARNING Exhaust heat/gases could ignite combustibles causing a fire, resulting in death or serious injury. • Remove all combustible materials from in and around the generator compartment. The unit has been set-up for NG operation at the factory. Fuel conversion, if needed, must be completed prior to performing these steps. See Fuel Conversion. Before operating the standby generator or placing it into service, inspect the entire installation carefully.

Important Owner's Considerations WARNING voltage is restored above a preset voltage level, the engine is signaled to shut down. The actual system operation is not adjustable and is sequenced by sensors and timers on the control board, as follows: Utility Voltage Dropout Sensor Engine exhaust contains carbon monoxide, a poisonous gas that could kill you in minutes. You cannot smell it, see it, or taste it. Even if you do not smell exhaust fumes, you could still be exposed to carbon monoxide gas.

n N o R tf ep o r ro du ct io Electronic Governor System The engine electronic governor system allows for improved control and increased generator performance compared to mechanically governed systems. The result is a smooth steady-state operation without the “hunting” common to many mechanical governors. The system also reduces speed variations under engine loading and unloading and significantly reduces frequency fluctuation experienced when the engine is under higher loads.
Service the Spark Plugs WARNING Unintentional sparking could cause fire or electric shock resulting in death or serious injury. WHEN ADJUSTING OR MAKING REPAIRS TO YOUR GENERATOR • Disconnect the spark plug wire from the spark plug and place the wire where it cannot contact spark plug. WHEN TESTING FOR ENGINE SPARK • Use approved spark plug tester. • DO NOT check for spark with spark plug removed. Changing the spark plugs will help your engine to start easier and operate better. 1.
