9.1.4 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.
ABB 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 ABB itself and ABB
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 Battery Test setting, a "Service Code" is required to enter user set-up parameters.
The start-up technician has access to this "Service 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 must 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 ABB Service Center to submit the form of Preventive Maintenance Contract
suitable for your specific needs.
