11.4 Battery Maintenance

CAUTION

！

・

Internal maintenance and inspection should be performed only by technically

qualified personnel. Electric shock, injury, burning, smoke or file could

otherwise result.

・

Batteries should be replaced periodically. Batteries used after their service life

has passed may cause a fire.

・

Never use organic chemicals such as gasoline, thinner, benzene or detergent to

clean batteries. These can cause the casing to crack and leak, resulting in fire

or current leakage.

(1) Battery backup time confirmation

Refer to §11.5 “Battery Test”, and periodically perform a battery backup time test.

Depending on the results of the test, exchange the battery.

The default Setup menu setting is to perform an automatic battery test once every 6

months.

(2) Estimated battery replacement interval

Battery service life is affected by operating conditions such as ambient temperature

and the number of discharge cycles. 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 average ambient temperature). Using

batteries after their service life has expired can cause leakage, and in the worst case

damage may result, so we recommend exchanging batteries early as a preventative

and protective step.

40°C (104°F) 1.7 years 1.5 years

(3) Battery specifications

The batteries in the UPS are specially designed for this application. Do not substitute

with any other type, and do not mix new and old batteries, as shortened battery life,

leakage, and heat could result.

(4) Battery disposal

Batteries are industrial waste containing lead, a toxic material and reusable resource.

Please cooperate by recycling when replacing or disposing of used batteries. To

dispose of used batteries, contact an authorized industrial waste handling company,

or repack them in their original cartons and send them to your supplier.
