Section 2 – Installation
PRIMEPACT 50 Recreational Vehicle Generator
2.8 BATTERY INSTALLATION | Figure 2.20 – Connecting Battery Cables |
◆2.8.1 RECOMMENDED BATTERY
Install a battery that meets the following requirements:
•The battery must be a
•For prevailing ambient temperatures above 32° F (0° C), use a battery rated 70
•For prevailing ambient temperatures below 32° F (0° C), use a battery rated 95
NOTE:
If the battery is to be used to power other vehicle accessories, as well as start the generator, you may need a battery with a larger capacity.
◆2.8.2 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 gen- erator connection point should not exceed 0.12 volts per 100 amperes of cranking current.
PRIMEPACT 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.
◆2.8.3 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 2.20).
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
3.Connect cables so the connectors are clean and tight.

◆2.8.4 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.
