DANGER A battery can present a risk of electrical shock and high short
circuit current.
The following precautions should be observed when working with batteries.
1) Verify that the “UPS” is off and that the Input Circuit Breaker is in the off position.
2) Remove watches, rings or other metal objects.
3) Use tools with insulated handles to prevent accidental shorts.
4) Wear rubber gloves and boots.
5) Do not lay tools or metal parts on top of batteries.
6)
Determine if the battery is grounded. If grounded, remove source of the ground.
Contact with any part of a grounded battery can result in an electrical shock.
Electrical shock will be reduced if grounds are removed during installation and maintenance.
7) Verify circuit polarities prior to making connections.
8) Disconnect charging source and load prior to connecting or disconnecting terminals.
9)
VRLA batteries contain an explosive mixture of hydrogen gas. Do not smoke; create a flame or a
spark in the immediate area of the batteries. This includes static electricity.
10)
Do not attempt to open the batteries in order to add water or sample the specific gravity of the
electrolyte. The batteries are valve regulated lead acid type and such servicing is not possible
without damaging the battery.
11)
Use proper lifting means when moving batteries and wear all appropriate safety clothing and
equipment.
12)
Dispose of lead acid batteries through proper channels in accordance with Local, State
and Federal EPA Regulations.
