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.

•Use a battery with minimum ratings of 70 amp- hours and 360 cold-cranking amps.

NOTE:

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

◆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 amps of cranking current.

The QUIETPACT™ 75D generator is rated at about 160 DC amps of cranking current to operate the starter and glow plugs.

Select battery cables based on (a) cable length and (b) prevailing ambient temperatures. Generally, the longer the cable and the colder the weather, the larg- er 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 insulated lug on the unit frame (Figure 2.19).

NOTE:

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

2.Connect the battery cable from the battery post, indicated by a NEGATIVE, NEG, or (-), to the vehicle frame ground connection (Figure 2.19).

3.Connect a cable from the vehicle frame ground to the negative post on the generator frame.

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