BATTERY
STORAGE BATTERIES GIVE OFF EXPLOSIVE HYDROGEN GAS. THIS GAS CAN
FORM AN EXPLOSIVE MIXTURE AROUND THE BATTERY FOR SEVERAL HOURS
AFTER CHARGING. THE SLIGHTEST SPARK CAN IGNITE THE GAS AND CAUSE AN
EXPLOSION. AN EXPLOSION CAN SHATTER THE BATTERY AND CAUSE BLIND-
NESS OR OTHER INJURY. ANY AREA THAT HOUSES A STORAGE BATTERY MUST
BE PROPERLY VENTILATED. DO NOT ALLOW SMOKING, OPEN FLAME, SPARKS,
OR ANY SPARK PRODUCING TOOLS OR EQUIPMENT NEAR THE BATTERY.
Battery electrolyte fluid is an extremely caustic sulfuric acid solution that can cause
severe burns. Do not permit fluid to contact eyes, skin, clothing, painted surfaces,
etc. Wear protective goggles, protective clothing and gloves when handling a battery.
If fluid is spilled, flush the affected area immediately with clear water.
Inspection
Note: See
Battery Safety
Every month, inspect the engine battery, as follows.
•
Check battery fluid level. Add distilled water, if needed.
•
Inspect battery cables and connections for cleanliness and corrosion.
Every six months, a GMPASD should inspect the battery system, as follows.
•
Check battery condition
•
Check battery charge using a battery hydrometer. Recharge or replace, as required.
Installation and Replacement
Note: See
Battery Safety
When required, the battery must be replaced with one of equivalent size, voltage, and CCA (cold crank amp capacity).
See unit specifications or contact a GMPASD for proper battery sizing. A new battery must be filled with the proper
electrolyte and be fully charged before installing.
Preliminary instructions:
1. Turn key switch to OFF.
2. Turn battery disconnect switch to OFF.
Battery cables are connected at the factor to the generator connection points. Connect cables to battery posts as
follows.
12VDC System:
Note: A negative ground system is used. Battery connections are shown in the wiring diagrams. Make sure the
battery is correctly connected and terminals are tight. Observe battery polarity when connecting the battery to the
generator set.
Explosion. Batteries emit explosive gases. Always connect positive battery cable first
to avoid spark. Failure to do so could result in death or serious injury. (000133)
