5.4 Installing the Battery
When you remove the battery from the carton, it is fully charged and ready for use.
NOTE:
You can install the battery without disconnecting the AC power source.
CAUTION
:
The storage container for the rechargeable battery must not be of sealed and air tight
construction. The container must be equipped with appropriate ventilation system, such as
ventilation holes leading to the outside and so on. The following applies to using a rechargeable
battery inside a metallic storage box: to prevent the rechargeable battery from leaking fluid due
to a breakage in the electrolytic cell, thus forming a leak circuit between the battery and the
storage box (or fixed frame), install between these two items a heat and acid resistant insulating
sheet (or tray) that will not be damaged by periodic stress. Alternatively, place the rechargeable
battery inside an insulating bag but not to be sealed.
For the above described insulation material, do not use any material that can be stained with
grease, or that can have organic substance oozing out of itself. Do not allow the rechargeable
battery to come into contact with vinyl tape containing plasticizer, insulation sheet, solvent, or
grease.
The battery compartment is located on the front of the DLC cabinet, as shown in Figure
