Section 4. Cabinet Battery Installation
Danger:
■ Batteries can be a lethal source of electrical power. Follow all locally approved safety practices.
■ Do not wear metallic jewelry, nor allow any tools to rest on batteries or lay across terminals.
■ Do not smoke, permit open flame, or cause sparks near a battery.
■ Keep batteries upright, and do not lift batteries at the terminals.
Caution:
■ Install batteries only after mounting the cabinet onto a concrete pad, steel plate or grate.
■ Do not lift the cabinet with the batteries installed, which may damage the cabinet.
■ Maximum amp hour per battery string should not exceed 190-amp hours.
■ There is risk of explosion if you replace one battery type with another. Dispose of used batteries
as instructed by the battery manufacturer.
■ Do not connect fewer batteries to a battery string than required, as thermal runaway can occur.
■ If battery storage temperature exceeds 32°C (90°F), the battery open circuit time should not
exceed four months.
■ Follow all battery and cabling instructions to reduce risk of fire, electric shock, and injury.
Important Safety Precautions:
■ For only one battery string, CommScope recommends loading battery shelf #1 first.
■ The customer shall incorporate a containment system within the battery compartment of the
cabinet to capture electrolyte in the case of a flooded battery.
■ Wear full eye protection and protective clothing.
■ If electrolyte contacts the skin, wash it off immediately with water.
■ Wash down spilled electrolyte with a suitable acid neutralizing agent.
Note: A usual practice is to apply a solution of about one-pound (500 grams) bicarbonate of
soda to one gallon (4 liters) of water. Carefully pour (add) the bicarbonate solution of
soda onto spilled electrolyte until evidence of reaction (foaming) ceases. Flush the
resulting liquid with water and allow area to dry.
► Battery Safety Recommendations
■ Always wear eye protection when installing and removing batteries. If exposed to electrolyte,
immediately soak eyes with plenty of water and seek medical attention as soon as possible.
■ Always keep water available for rinsing and washing.
■ For skin protection, wear protective clothing such as, rubber gloves and long sleeves, including safety
glasses (or a face shield).
■ For protection of clothing, wear rubber or plastic aprons or other appropriate protection.
■ Keep batteries upright to prevent spillage.
Note: In case of spillage do not dispose of electrolyte in public drainage systems. Use an
appropriate absorbent material to remove electrolyte. Refer to the MSDS for procedure
guidelines and consult with the manufacturer representative for available spill kits.
■ Always keep battery covers in place prior to installation.
■ Use a multimeter to verify polarity when connecting string to the system. Never rely on color. Color-
coded battery terminals and color-coded system wires are not always polarity compatible.
■ Always ground yourself, your tools, or anything else when working on batteries to prevent accidental
sparks from static electric discharge.
■ Take extra care to prevent static electricity during days of low humidity. Touch the outside of the
cabinet, or any grounded metal structure to eliminate static electric discharge.
■ Use the battery handles when lifting batteries. Batteries are heavy, handle and lift appropriately.
