Recreational Vehicle Generator

2.Connect the battery cable from the battery post indicated by a NEGATIVE, NEG or (-) to the frame ground connection (Figure 2.16).

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

2.7BATTERY INSTALLATION

‹2.7.1 RECOMMENDED BATTERY

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.

3.Connect cables so the connectors are clean and tight.

‹2.7.4 BATTERY COMPARTMENT

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.

‹2.7.2 BATTERY CABLES

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 chart.

CABLE LENGTH
in Feet (Meters)	CABLE SIZE
0 to 10 (0 to 3)	2*
11 to 15 (3.4 to 4.5)	0
16 to 20 (4.5 to 6)	000

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

‹2.7.3 BATTERY CABLE CONNECTIONS

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.

2.8OPTIONAL ACCESSORIES

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.
