8 - Maintenance
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.
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 immediately with plenty of water, if eye contact occurs
flush with water and contact a physician.
8.4 Safety
CAUTION:
When the UPS is operating, all parts of the electronics are directly connected to the utility and high
voltages are present on all internal parts, including the battery. Even after disconnection from the
utility, all parts inside the UPS, including the battery, conduct dangerous voltages (except the RS232
output).
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: every 3 months, for 24 hours,
- if the storage temperature is within -20 and +45°C: every month, for 24 hours.
8.6 Recycling the UPS at the end of service life
NOTE
: This product has been designed to respect the environment, using materials and components
respecting eco-design rules. It does not contain CFCs (Carbon Fluor

GE Digital Energy, in compliance with environment protection recommends that the UPS equipment,
at the end of its service life, must be recycled conforming to the local applicable regulations.
WARNING
The batteries contain lead, which is a dangerous substance for the environment. Therefore the
batteries must be recycled correctly by specialized companies.
