9 MAINTENANCE
WARNING !
All maintenance and service works must be performed by QUALIFIED SERVICE
PERSONNEL.
9.1 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 power supply.
GE’s Critical Power recommends to perform the first service within 12 months from the commissioning
date or within 18 months from delivery date.
Subsequent services to perform every 12 months.
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.
9.1.1 Service check
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.
Some components of the UPS which need periodic maintenance, if not replaced, could cause a reliability
reduction of the supply system
We highly recommend that you contact your Service Center for preventive maintenance work.
9.1.2 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.
The fans eventually wear out and must be substituted when a UPS alarm is triggered, in order to ensure
the reliability of the UPS
9.1.3 Other components with limited lifetime
Various components, such as the DC and AC filter capacitors and the lithium battery on the “P3 -Control
Panel” (memory saving), must be systematically substituted in order to maintain the UPS’S reliability.
The substitution of these components is signaled by a UPS alarm going off.
