Generac Power Systems 004701-0 用户手册

The power supply cord must comply with all appli-
cable codes, standards and regulations. It must be 
large enough to handle the full amperage to which it 
will be subjected.

The National Electrical Code (NFPA 70, 551-7) 
requires that a ground fault circuit interrupters 
(GFCIs) be installed on all external and some internal 
electrical receptacles. Contact the dealer for recom-
mendations.

Install a battery that meets the following require-
ments:

• The battery must be a 12-volt, automotive type 

storage battery.

• For prevailing ambient temperatures above 32° 

F (0° C), use a battery rated 70 amp-hours and 
capable of delivering 400 cold-cranking amperes.

• For prevailing ambient temperatures below 32° 

F (0° C), use a battery rated 95 amp-hours and 
capable of delivering 400 cold-cranking amperes.

NOTE:

If the battery is to be used to power other vehicle 
accessories, as well as start the generator, a bat-
tery with a larger capacity may be needed.

Using battery cables that are too long or too small in 
diameter may cause a drop in voltage, which causes 
starting problems. For the best cold weather starting, 
the voltage drop between battery terminals and the 
generator connection point should not exceed 0.12 
volts per 100 amperes of cranking current.

These generators are rated at about 100 DC amperes 
of cranking current.

Select battery cables based on (a) cable length and 
(b) prevailing ambient temperatures. Generally, the 
longer the cable and the colder the weather, the larger 
the cable size must be, as shown in the following 
chart.

* For warm weather, use No. 2 cable up to 20 feet.

1.  Connect the battery cable from the battery post or 

terminal indicated by a POSITIVE, POS or (+) to 
the lug on the starter contactor (Figure 2.16).

NOTE:

Check to be sure the battery cable boot for the 
starter cable has been installed.

2.  Connect the battery cable from the battery post 

indicated by a NEGATIVE, NEG or (-) to the 
frame ground connection (Figure 2.16).

3.  Connect cables so the connectors are clean 

and tight.

CONNECTION

Install the generator battery in its own, vented com-
partment. Place the battery compartment away from 
any source of heat, sparks or flame.

Provide ventilation openings in the battery compart-
ment. The minimum size of openings should be 2 
square inches at the top of the compartment. Mount 
the battery on a strong, rigid supporting structure, 
where leaks and spills of battery fluid will not cause 
damage.

A plug-in receptacle (Figure 2.17) is provided on 
the generator set. Use this receptacle to connect an 
optional remote-mounted start/stop panel to the 
generator. Installation of such a panel will permit 
starting and stopping the generator engine from any 
convenient location inside the vehicle.
