8.1
General
When used properly, the UPS is virtually maintenance free other than keeping the air inlets/outlets free from dust.
8.2
Cooling fan
The expected operational life of the cooling fans is approximately 20,000 to 40,000 hours of continuous operation. A
high ambient temperature will shorten this operational life.
8.3
Batteries
The service life of the battery is from 3 to 6 years, depending on the operating temperature and on the number of
discharge cycles.
As a healthy battery is essential to the performance of the UPS, an automatic battery test is performed regularly to
ensure failsafe operation (see section 5.4.1). When the condition of the battery is critical, the warning signal will be
activated (buzzer 1x per 8 secs, and alarm message 'Replace battery', see 5.3.2). The batteries must be replaced
as soon as possible. Please contact your dealer. Use only UL recognised batteries (BAZR2), valve regulated
types.
NOTE: under certain circumstances a manual battery test can result in a false alarm: please see section 5.4.2
'QUICK BATTERY TEST'.
Regular deep battery tests are advised in order to re-calibrate the capacity of aging batteries. See section 5.4.3 for
more information.
NOTE: All maintenance and service work, including battery replacement, should be performed by qualified
service personnel.
For authorized service personnel only:
Never short the battery terminals. Shorting may cause the battery to burn. Avoid charging in a sealed container.
Proper disposal of batteries is required: refer to your local codes for disposal requirements. Never dispose of
batteries in a fire: they may explode. Never disassemble or reassemble batteries; their contents (electrolyte) may be
extremely toxic. If exposed to electrolyte, wash immeditately with plenty of water, if eye contact occurs flush with
water and contact a physician.

For your safety, only authorized service personnel may remove the cabinet cover.
8.5
Storage
Always store the UPS in a dry location with the batteries in a fully charged state, storage temperature must be within
-20 and +45°C. Storing the unit for a period exceeding 3 months can reduce the life of the batteries. To maintain
their normal life expectancy, the batteries must be recharged periodically:
-
if the storage temperature is within -20 and +30°C (-4°F and 86°F): every 6 months, for 24 hours,
-
if the storage temperature is within -20 and +45°C (-4°F and 113°F): every 4 months, for 24 hours.
