8 - MAINTENANCE
NOTE
Refer maintenance and service work, including battery replacement, to GE Authorized Service
station.
Refer to section 1.3 for further details.
8.1 - SAFETY
DANGER
When the UPS operates, 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.
Refer to section 1.3 for further details
8.2 - GENERAL
When used properly, the UPS is virtually maintenance free other than keeping the air inlets/outlets free from dust.
8.3 - 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.
8.4 - 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 5.5.1). When the condition of the battery is critical, the warning signal will be
activated (buzzer 1x per 8 seconds, and alarm message 'Replace battery', see 5.4.2). The batteries must be replaced as
soon as possible. Please contact your dealer. Use only UL recognized batteries (BAZR2), valve regulated types and the
part number recommended by the GE Authorized representative.
NOTE: under certain circumstances a manual battery test can result in a false alarm: please see section 5.5.2 'QUICK
BATTERY TEST'.
Regular deep battery tests are advised in order to re-calibrate the capacity of aging batteries. See section 5.5.3 for more
information.
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.
