Safety precautions
Do not drop the battery or do not give strong impact on it.
●
Dilute sulfuric acid may leak.
Do not short the battery with metal objects.
●
Doing so could cause an electric shock, fire or burn.
●
Some electrical energy still remains inside the spent battery.
Do not dispose of batteries in a fire.
●
The batteries may explode. Dispose of used batteries according to the instructions.
Replacement of batteries located in a SERVICE ACCESS AREA
1) Servicing of batteries should be performed or supervised by personnel knowledgeable about
batteries and the required precautions.
2) A battery can present a risk of electrical shock and high short circuit current. The following
precautions 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 battery is inadvertently grounded. If inadvertently grounded, remove source
from ground. Contact with any part of a grounded battery can result in electrical shock.
The likelihood of such shock can be reduced if such grounds are removed during installation
and maintenance (applicable to equipment and remote battery supplies not having a
grounded supply circuit).
Notes
When moving the unit from a cold place to a warm place, leave it for several hours
before using it.
●
If the unit is moved to a warmer place and the power is turned on soon, the unit failure may occur due to
condensation to the unit.
Charge the battery for at least 12 hours soon after purchasing the unit.
●
If you do not use the unit for a long time after the purchase, the property of the battery may deteriorate and
the battery may become unusable.
●
To charge a battery, connect the AC input plug of the unit to a wall outlet (commercial power).
When storing the unit, charge the battery for at least 12 hours and turn off the power switch.
●
Even if the unit is not used, the battery gradually discharges, and if it is left for a long time, it goes into an
over discharge state.
The backup time may become shorter or the battery may become unusable.
●
We recommend keeping the temperature 40
°
C or less when storing the unit for long periods of time.
Connect the unit’s AC input plug to a wall outlet (commercial power) for at least 12 hours at the following
intervals:
- Every 6 months when storage temperature is 25
°
C or less
- Every 2 months when storage temperature is 40
°
C or less
●
Turn off the power switch of the unit during storage.
Do not short the output lines of the unit each other and the output lines to the ground.
●
The unit may fail.
