12Vdc Battery Charger - Generac Power Systems Digital Controller R-200A Technical Manual

DANGER

Storage batteries give off explosive hydrogen
gas. This gas can form an explosive mixture
around the battery for several hours after charg-
ing. The slightest spark can ignite the gas and
cause an explosion. Such an explosion can shat-
ter the battery and cause blindness or other
injury. Any area that houses a storage battery
must be properly ventilated. Do not allow smok-
ing, open flame, sparks or any spark producing
tools or equipment near the battery.

Battery electrolyte fluid is an extremely corro-
sive 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.

Do not use any jumper cables or booster battery
to crank and start the generator engine. If the
battery has completely discharged, remove it
from the generator for recharging.

Be sure the AUTO/OFF/MANUAL switch is set to
the OFF position, before connecting the battery
cables. If the switch is set to AUTO or MANUAL,
the generator can crank and start as soon as the
battery cables are connected.

Be sure the utility power supply to the battery
charger is turned off, or sparking may occur at
the battery posts as the cables are attached and
cause an explosion.
