6. Notes for handling of battery
•
Servicing of batteries should be performed or supervised by personnel knowledgeable of
batteries and the required precautions. Keep unauthorized personnel away from batteries.
•
When replacing batteries, replace with the same number of the type “HF7-12”.
•
Do not dispose of used battery by the customer. When disposing of used battery, always contact
your nearest sales representative, authorized service center, or sales office
•
Do not use a battery, the service life of which has expired. Doing so may cause fuming or fire to
be produced. Additionally, if such battery is used continuously, the battery backup function is
not activated even if a power outage occurs, causing load units to stop
•
A battery can present a risk of electrical shock and high short circuit current. The following
precaution should be observed when working on batteries:
a. Remove watches, rings or other metal objects.
b. Use tools with insulated handles.
c. Wear rubber gloves and boots.
d. Do not lay tools or metal parts on top of batteries.
e. Disconnect charging source prior to connecting or disconnecting battery terminals.
f. Determine if the battery is inadvertently grounded. If inadvertently grounded, remove
source of ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock will be reduced if such grounds are removed during installation
and maintenance
•
Do not open or mutilate the battery or batteries. The battery contains dilute sulfuric acid, which
is extremely toxic. If the battery fluid leaks, take approximate measures so that the leak battery
fluid is not sticking to your skin or clothing. If dilute sulfuric acid enters your eye, this may
cause eyesight to be lost. Additionally, if dilute sulfuric acid is in contact with your skin, this
may cause a burn.
It is electrically conductive and corrosive. The following procedures
should be observed:
a. War full eye protection and protective clothing.
b. If electrolyte contacts the skin, wash it off immediately with water.
c. If electrolyte contacts the eyes flush thoroughly and immediately with water. Seek
medical attention.
d. Spilled electrolyte should be washed down with a suitable acid neutralizing agent. A
common practice is to use a solution of approximately one pound (500 grams)
bicarbonate of soda to approximately one gallon (4 liters) of water. The bicarbonate of
soda solution should be added unit the evidence of reaction (foaming) has ceased. The
resulting liquid should be flushed with water and the area dried.
•
Lead acid batteries can present a risk of fire because the generate hydrogen gas. The
following procedures should be followed:
a. DO NOT SMOKE when near batteries.
b. DO NOT cause flame or spark in battery area.
c. Discharge static electricity from body before touching batteries by first touching a
grounded metal surface.
•
Do not dispose of battery or batteries in a fire. The battery may explode.
•
If a fire occurs in the battery, do not use water to put off the fire. Always use powder-
distinguishing agent (ABC). If water is used, the fire may be expanded.
•
Always strictly observe the following cautions when handling the battery. Failure to do so may
cause leak battery fluid, heat, or explosion.
a. Do not solder any part to the battery directly
b. Do not charge the battery with the positive (+) and negative (
-
) terminals used reversely.
c. Do not mix batteries with different types, manufacturers, and/or versions.
d. Do not peel off or break the outer packing tube of the battery.
e. Do not apply a strong impact to the battery or throw away the battery.
f. Clean the battery with wet cloth rag. Do not use organic compound such as gasoline,
thinner and benzene or detergent.
g. The electric energy may remain in the battery even after its service life has expired.
Do not apply sparks to the used battery or make it short-circuited.
