11 MAINTENANCE
WARNING !
All maintenance and service works must be performed by QUALIFIED SERVICE PERSON.
11.1 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 Centre
organisation.
11.2 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.
11.3 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
.
11.4 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
LP 33 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 mains 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 Centre
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
Centre Service
.
11.5 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.
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 Centre
for preventive maintenance work.
NOTE !
Ask to your local
Service Centre
to submit the form of
Preventive Maintenance
Contract
suitable for your specific needs.
