◆ 11.4 Battery Maintenance and Inspection
！
CAUTION
(1) Battery Backup Confirmation
Battery backup capacity should be tested periodically (about once every 3 months),
according to § 12.1, "Battery Test". As a result of battery test, if the battery replacement is
required, please contact your nearest sales representative.
(2) Battery Replacement Period Prediction
Battery life is affected by operating conditions such as ambient temperature and number
of discharges. Ambient temperature has a particularly strong influence as indicated in
the following table (refer to the table to predict when batteries will need to be replaced
according to ambient temperature). Using batteries after their life expectancy can cause
leakage, and in the worst case damage may result, so we recommend changing batteries
early as a preventative and protective step.
Ambient Operating
Temperature
25 ° C (77 ° F)
30 ° C (86 ° F)
35 ° C (95 ° F)
40 ° C (104 ° F)
(3) Battery Specification
The batteries used in the UPS are specially designed for this application. Do not
substitute with any other type, and do not mix brands or new and old batteries, as
shortened battery life, fluid leakage and overheating could result.
(4) Used Battery Disposal
Batteries include poisonous lead substances, so to dispose of used batteries after
replacement, please contact a waste disposal/recycling company, or return batteries to the
place of purchase using the packaging in which the replacement batteries were supplied.

personnel. Electric shock, injury, burning, smoke or file could otherwise
result.
CAUTION
During bypass operation (OUTPUT LED blinking), if the red ALARM indicator is lit, a
blown Bypass fuse may be suspected. In this case, please contact your nearest sales
representative.
Battery replacement should be performed only by technically qualified

personnel. Electric shock, injury, burning, smoke or file could
otherwise result.
Batteries should be replaced periodically. Batteries that have passed
•
their service life may cause a fire.
Do not use organic solvents such as gasoline, thinner and benzene, or
•
other cleaning compounds. These can adhere to seams in the battery
casing, causing current leakage or fire.
