Battery
NOTE !
Perform mandatory battery maintenance per battery’s manufacturer product
manual. This includes electrical and thermal measurements, inspection, cleaning,
replacement and re-torque of connections.
Failure to perform proper maintenance on the battery, per the battery
manufacturer’s recommendation, including scheduled battery replacement, may
result in thermal damage to the equipment and an increased risk of personnel
injury.
GE declines any responsibility for any damage to the system and the surrounding
caused by battery when the battery maintenance program is provided by other than
GE itself and GE authorized partners.
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 that this test is 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 & Manual 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.
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.
9.1.5
UPS room conditions and temperature
The UPS room and the
Battery Room
have to be maintained clean and free from dust.
A high temperature of the UPS room and of the
Battery Room
affect the lifetime of several components
inside the equipment.
The
Battery
is very sensitive to room temperatures above
77°F
(25°C).
9.1.6
Preventive maintenance program
a)
Cleaning, a visual inspection and a mechanical inspection of the UPS modules.
b)
Replacement of defective parts or the preventive replacement of parts with a defined lifetime.
c)
“Updating” of the equipment (technical improvements subsequent to the delivery).
d)
Check the calibration of
DC voltage
and
Inverter Output Voltage
and
Frequency
.
e)
Check of the settings of the electronic regulation, the control and the alarm circuits of the
Rectifier(s)
and
Inverter(s)
.
f)
Functional checks on
Thyristors
,
Diodes
,
Transformers
,
Filter Components
, e.g. to ensure that they
are operating within the specified design parameters.
g)
Overall performance test including a
Utility Failure
simulation with and without the
Load
.
h)
Monitoring
Battery
operation in discharge and recharge mode including any boost charge duties.
NOTE !
Ask to your local GE Service Center to submit the form of Preventive Maintenance
Contract
suitable for your specific needs.
