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.
