WARNING

Sulfuric acid in batteries.

Can cause severe injury or death.

Use protective goggles and clothes. Battery acid can cause permanent damage to eyes, burn skin, and eat holes in clothing.

Battery gases. Explosion can cause severe injury or death. Battery gases can cause an explosion. Do not smoke or permit flames or sparks to occur near a battery at any time, particularly when it is charging. Do not dispose of a battery in a fire. To prevent burns and sparks that could cause an explosion, avoid touching the battery terminals with tools or other metal objects. Remove all jewelry before servicing the equipment. Discharge static electricity from your body before touching batteries by first touching a grounded metal surface away from the battery. To avoid sparks, do not disturb the battery charger connections while the battery is charging. Always turn the battery charger off before disconnecting the battery connections. Ventilate the compartments containing batteries to prevent accumulation of explosive gases.

Starting battery. A separate 12-volt battery is recommended for the generator set. With a separate battery, the battery can be installed closer to the generator set and the cable length can be minimized to eliminate voltage drop. See Figure 6-4 for the minimum cold cranking amps (CCA) battery recommendation.

Cable connections. See Section 7 for the battery positive and negative connection points. Refer to Figure 6-6 (View A) for cable connections. (Note that installers must connect a ground strap between the ground lug on the generator set and the frame of the vehicle with this arrangement.)

For installations where the starting battery for the vehicle engine must also be used for starting the generator engine, ground the negative battery terminal to the vehicle frame and connect a heavy gauge (#4) ground strap to the ground lug on the generator set to the vehicle frame as illustrated in Figure 6-6 (View B).

Note: Ensure a ground connection between the generator and the vehicle frame even if the battery used to start the generator is not the same as the vehicle.
