Liquid-cooled 30 kW Generators

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 caus- tic 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 the fluid is spilled, flush the affected area immediately with clear water.

Spilled electrolyte is to be washed down with an acid neutralizing agent. A common practice is to use a solution of one pound (500 grams) bicarbonate of soda to one gallon (4 liters) of water. The bicarbonate of soda solution is to be added until the evidence of reaction (foaming) has ceased. The resulting liquid is to be flushed with water and the area dried.

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.

Ensure that the 15A and 4A fuses are removed from the control console, the AUTO/OFF/ MANUAL switch is set to OFF, and the utility supply to the battery charger is removed before removing or connecting battery cables. If the switch is set to AUTO or MANUAL, the genera- tor 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.
