9 MAINTENANCE
WARNING !
All maintenance and service works must be performed by QUALIFIED SERVICE
PERSON.
9.1 GENERAL MAINTENANCE
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 Center
organization.
9.2 COOLING FAN MAINTENANCE
The expected operational life of the cooling fans is approximately 40,000 hours of continuous
operation. A high ambient temperature will shorten this operational life.
9.3 OTHER COMPONENTS WITH LIMITED LIFETIME
We recommend the replacement of components such as AC and DC Capacitors every 50,000 hours.
9.4 BATTERY MAINTENANCE
The service life of the battery is from 3 to 6 years, depending on the operating temperature and on the
number of discharge cycles.
The UPS LP33 Series offers the possibility of SBM (Superior Battery Management).
The function SBM can be activated through a service Parameter.
The functionality of SBM reduces the Battery recharging time together with improved lifetime of the
Battery.
As a healthy battery is essential to the performance of the UPS, an automatic or manual battery test
can be performed regularly to ensure failsafe operation, in order to check if the battery can provide the
expected backup time in case of utility failure.
We recommend the battery test be performed at least every 1 month, especially if the battery is not
sufficiently discharged during normal operation.
Since the parameter enabling the battery test protected by user password, please contact your Service
Center for more information.
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.
To guarantee that the battery is fully charged, the UPS system should be in operation for at least 12
hours every 3 months.
When the condition of the battery is critical, the warning signal will be activated (general alarm, buzzer
and alarm message “4118 - Battery fault”).
In this case the battery must be replaced as soon as possible.
Please contact your Service Center.
9.5 SERVICE REQUIRED
If this lamp lights up during normal operation, the unit has not been serviced for the last 20,000 hours
by a GE trained technician.
We highly recommend that you contact your Service Center for preventive maintenance work.
NOTE !
Ask to your local Service Center to submit the form of Preventive Maintenance
Contract suitable for your specific needs.
