Chapter 7 Maintenance And Troubleshooting

This chapter introduces the UPS maintenance, including fan maintenance, battery maintenance, UPS cleaning, UPS
state checking, UPS functions checking and troubleshooting.

7.1 Fan Maintenance

The UPS fans can run for 20000 hours ~ 40000 hours continuously. The higher the ambient temperature is, the
shorter the life time of the fan will be.
During the UPS operation, periodically check the status of all fans once every half year to confirm that the airflow can
blow out from the ventilation holes on the rear panel of the UPS.

7.2 Battery Maintenance

1. Never short the battery, otherwise a fire will occur.
2. Never open the battery so as to prevent the electrolyte from hurting human body. If you touch the electrolyte inadvertently, wash
the area immediately with plenty of clean water and go to hospital.
The internal battery of the battery module option uses sealed, maintenance-free, lead-acid battery. The battery life
time depends on ambient temperature, charging and discharging time. High-temperature environment or deep
discharge will shorten the battery life time.
To ensure the battery life time, the following maintenance should be conducted periodically:
 Maintain the ambient temperature between 15° C and 25° C
 Prevent the battery from small current discharge. The continuous operation time of the UPS battery is prohibited
to exceed twenty four hours in any condition
 Charge the battery for at least twelve hours when the UPS is not used for a long time or the battery has not
been charged or discharged for three months continuously. In high-temperature environment, charge the battery
for at least twelve hours when the battery has not been charged or discharged for two months continuously
1. Periodially check that the screws that fix the battery connection parts is tightened. If any screw is loose, tighten it immediately.
2. Ensure that all safety equipment are complete and that the functions are normal, especially that the settings of battery
management parameters are normal.
3. Measure and record the temperature inside the battery room.
4. Check whether the battery ports are damaged or hot, and whether the enclosures or covers are damaged.
If the liquid leakage or damage to the battery occurs, place the battery in the anti-vitriolic tank and conduct rejection
treatment according to local regulations.
Waste lead-acid battery is dangerous waste material, and one of the national emphases to control waste battery
pollution. Its storage, transportation, utilization, disposal must observe national and local laws, regulations and other
criterions about the dangerous waste materials and waste battery pollution prevention and cure.
According to related national regulations, the waste lead-acid battery should be recycled and it is forbidden to use
other disposal methods. Throwing away randomly the waste and old lead-acid battery or other improper disposal
methods may result in serious environmental pollution, which will be investigated the relevant legal responsibility.
As the lead-acid battery supplier, Emerson has built perfect service network and recycle system for the waste battery
to assist the user to deal with the waste and old lead-acid battery by law. Contact Emerson or nearby office to obtain
the detailed information of Emerson recycle system about waste and old battery.
