battery must be connected to the generator DC terminals with the proper polarity (battery positive to
generator red terminal and battery negative to the generator black terminal.)
DC Circuit Protector
The DC circuit protector automatically shuts off the DC battery charging circuit when the generator is
overloaded, when there is a problem with the battery or the connections between the battery and the
generator are improper.
GENERATOR USE
Connections to a Building’s Electrical System
Connections for standby power to a building’s electrical system must be made by a qualified electrician.
The connection must isolate the generator power from utility power, and must comply with all
applicable laws and electrical codes.
Improper connections to a building’s electrical system can allow electrical current from the
generator to back feed into the utility lines. Such back feed may electrocute utility company
workers or others who contact the lines during a power outage. Consult the utility company or
a qualified electrician.
Improper connections to a building’s electrical system can allow electrical current from the
utility company to back feed into the generator. When utility power is restored, the generator
may explode, burn, or cause fires in the building’s electrical system.
In some areas, generators are required by law to be registered with local utility companies. Check
local regulations for proper registration and use procedures.
Generator Ground Circuits
Portable generators have a system ground that connects the generator frame components to the
ground terminals in the AC output receptacles. The system ground is not connected to the AC neutral
wire. Local regulations, codes or laws may require that the ground system be connected to the AC
neutral wire. If the generator is tested by a receptacle tester, it will not show the same ground circuit
condition as for a home receptacle. If local regulations, codes, or laws require the system ground to be
connected to the AC neutral wire, consult a qualified electrical or electrical inspector. Provide him with
the electrical wiring diagram in this manual.
The ground terminal can be used to ground the generator or bond the frame of the generator to the
frame of a vehicle, but only if it is required by local law or electrical code. Before using the ground
terminal consult a qualified electrician or electrical inspector for regulations in your area.
AC Applications
Before connecting an appliance or power cord to the generator make sure that it is in good working
order. Faulty appliances or power cords can create a potential for electrical shock. If an appliance
begins to operate abnormally, becomes sluggish or stops suddenly, turn it off immediately. Disconnect
the appliance, and determine whether the problem is the appliance, or if the rated load capacity of the
generator has been exceeded. Make sure that the electrical rating of the tool or appliance does not
