Chapter 7 Maintenance And Troubleshooting
This chapter introduces the UPS maintenance, including fan maintenance, battery maintenance, cleaning UPS,
checking UPS status, checking UPS functions and troubleshooting.
7.1 Fan Maintenance
The UPS fans are intended to run for 20000 hours ~ 40000 hours continuously. The higher the environmental
temperature is, the shorter the fan life will be.
During UPS operation, verify the fan status once every half a year by confirming that the airflow can blow out from the
ventilation holes on the rear panel of the UPS.
7.2 Battery Maintenance
Note
1. Never short connect the battery, otherwise a fire will occur.
2. Never open the battery to prevent physical injury because of the electrolyte. If you accidentally touch the electrolyte, wash the
area immediately with plenty of clean water and go to hospital.
The internal battery of the UPS is sealed, lead-acid, maintenance-free battery. The battery life depends on the
environmental temperature, charge and discharge times. High environmental temperature and deep discharge
shortens the battery life.
To ensure the battery life, it is required to:
Maintain the environmental temperature between 15°C and 25°C.
Prevent small current discharge. Continuous battery operation time exceeding 24 hours is strictly prohibited.
Charge the battery for at least 12 hours when the UPS is not in use 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 12 hours when the battery has not been charged or discharged for two months continuously.
Note
1. Check the screws that fix the battery connecting components periodically. If the screws are loose, tighten them immediately.
2. Ensure that all safety equipment is complete and that the function is normal, especially that the settings of the battery
management parameters are correct.
3. Measure and record the temperature of the battery room.
4. Check whether the battery ports are damaged or hot, and whether the enclosure and the covers are damaged.
If liquid leakage and damage to the battery are found, place the battery in the anti-vitriol tank, and deal with it
according to the local regulations.
The waste lead-acid battery is dangerous waste material. It is one of the national emphases to control the waste
battery pollution. Its storage, transportation, usage and disposal must follow the national and local law and other
criterions about the dangerous waste material and the waste battery pollution prevention.
According to the related regulations, recycle the waste lead-acid battery, and other disposal methods are prohibited.
Throwing away randomly the waste lead-acid battery and other improper disposal methods can result in serious
environment pollution, which will be investigated the legal responsibility.
As the provider of the lead-acid battery, Emerson has built perfect service network and recycle system for the waste
battery to assist users to deal with the waste battery by law. Contact Emerson or the nearest service center for the
detailed information of the recycle system about the waste battery.
Emerson is not liable for the environment results caused by failure to comply with the notices in this section or to use
the waste battery recycle system provided by Emerson.
