10 MAINTENANCE
10.1 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 critical
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 GE Global Services
@ 1-800-637-1738
10.1.1 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 a GE trained technician.
We highly recommend that you contact your
Service Center
for preventive maintenance work.
10.1.2 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
.
10.1.3 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.
10.1.4 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 Utility
Failure.
We recommend this test be performed at least every 3 months, 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.
The start up technician has access to this code and can program this feature during start up.
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.
