11 MAINTENANCE

WARNING !
All maintenance and service works must be performed by QUALIFIED SERVICE
PERSONNEL.
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.
Service check
If this lamp lights up during the normal operation, that means that the unit has not been serviced for the
last 20'000 hours by an GE trained technician.
We highly recommend that you contact your Service Centre for preventive maintenance work.
Fans and ventilation
We recommend a periodic cleaning of the ventilation channels and grids on the UPS system, in order to
guarantee proper air circulation in the unit and in the battery.
We recommend replacement of the fans in the units every 20'000 hours.
Other components with limited lifetime
We recommend the replacement of components such as filter capacitors and lithium battery for the
backup of data on the control boards of the units every 50'000 hours.
Battery
We recommend a periodic manual battery test, especially if the automatic battery test is disabled, in
order to verify if the battery can provide the expected backup time in case of mains failure.
We recommend this test be performed at least every 1 month, especially if the battery is not sufficiently
discharged during normal operation.
The discharge time you use should be at least half of the battery runtime.
For automatic battery test setting, a special code is required to enter User set-up parameters.
Please consider that, if you did a full battery test to verify the full runtime of the battery, the charger
needs at least 8 hours to recharge the battery up to 90% of its capacity.
Long shut-down periods of the UPS-system
To guarantee that the battery is fully charged, the UPS system should be in operation for at least 12
hours every 3 months.
If not the battery may be permanently damaged.
