1100RE 24 VDC 960 Ah Battery Bank Installation

2.3.2 Explosive Gases

Batteries can generate gases, which when released can explode,

causing blindness and other serious personal injury.

Always wear protective clothing and use the correct safety tools.

Eliminate any potential of sparks, flames or arcing.

IN CASE OF FIRE: To extinguish a fire in a battery room containing lead-acid batteries, use a

CO2, foam or dry-chemical extinguishing medium. Do NOT discharge the extinguisher directly

onto the battery. The resulting thermal shock may cause cracking of the battery case/cover.

SPECIAL PROCEDURES:

If batteries are on charge, shut off power. Use positive-pressure, self-contained breathing

apparatus. Wear acid resistant clothing. Water applied to electrolyte generates heat and

causes it to splatter.

TOXIC FUMES:

Burning plastic may cause toxic fumes. Leave area as soon as possible if toxic fumes

are present. Wear breathing apparatus if required to remain in the area.

2.3.3 Electrical Shocks and Burns

Multi-cell battery systems can attain high voltage and/or currents. Do NOT

touch uninsulated batteries, connectors or terminals. To prevent serious

electrical burns and shock, use EXTREME CAUTION when working with

the system.

Always wear protective clothing and use nonconductive or insulated safety tools when

working with ANY battery system.

Remove all jewelry that could produce a short circuit.

BEFORE working on the system:

1. Disconnect ALL loads and power sources to the battery. Use appropriate

lockout/tagout procedures.

2. If working on an assembled battery system, sectionalize (interrupt the battery

sections) into safe working voltage levels.

3. Check the battery system grounding. Grounding of the battery system is NOT

recommended. However, gr

ounding of the rack is recommended.
