4.9.3— Battery Inspection
*
Stationary emergency generators installed with automatic transfer switches will crank and start auto-
matically when NORMAL (UTILITY) source voltage is removed or is below an acceptable preset level.
To prevent automatic startup and possible injury to personnel, do not connect battery cables until
NORMAL source voltage at the transfer switch is correct and the system is ready to be placed into
operation.
$
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 blindness 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, pro-
tective clothing and gloves when handling a battery. If fluid is spilled, flush the affected area immedi-
ately with clear water.
$
DO NOT dispose of the battery in a fire. The battery is capable of exploding.
*
DO NOT open or mutilate the battery. Released electrolyte can be toxic and harmful to the skin and
eyes.
+
The battery represents a risk of high short circuit current. When working on the battery, always
remove watches, rings, or other metal objects, and only use tools that have insulated handles.
An authorized operator should inspect the engine battery system monthly. At this time, the battery fluid level should be
checked and distilled water added if needed. Battery cables and connections also should be inspected for cleanliness
and corrosion.
Once every six months, an Authorized Service Technician should inspect the battery system. At this time the battery
condition and state of charge should be checked using a battery hydrometer. The battery should be recharged or
replaced as required.
*
Servicing of the battery is to be performed or supervised by personnel knowledgeable of batteries
and the required precautions. Keep unauthorized personnel away from batteries. Observe the follow-
ing precautions when working on batteries:
•
Remove the 10A F2 fuse from the generator control panel.
•
Remove watches, rings, or other metal objects.
•
Use tools with insulated handles.
•
Wear rubber gloves and boots.
•
Do not lay tools or metal parts on top of the battery.
