7. MAINTENANCE
7.1
GENERAL
A UPS system, like other electrical equipment, needs periodic preventive maintenance.
A regular maintenance check of your installation guarantees higher reliability of your safe
power supply.
Preventive maintenance work on the UPS can be done only by trained
Service technicians
.
We therefore recommend you sign a Maintenance and Service contract with the local
Service Centre
organisation.
7.2
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.
7.3
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 chapter 4.4.1).
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 chapter 4.3.2).
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 chapter 4.4.2 - “QUICK BATTERY TEST”.
Regular deep battery tests are advised in order to re-calibrate the capacity of ageing batteries.
See chapter 4.3.3 for more information.
•
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 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, when acid contacts ones
eyes wash them with a lot of water and see a doctor.
