8 Maintenance
This chapter focuses on the UPS maintenance, including the fan maintenance, battery maintenance, UPS
cleaning, UPS state check, UPS function check.
NOTE: Never attempt to carry out maintenance on the UPS while it is on line. Ensure that the UPS has
been switched off completely when performing any internal maintenance operations on it.
8.1 Fan Maintenance
NOTE: In order to avoid injury or damaging the device, wait until the fan is completely stationary before
inserting fingers or any tools into it.
The UPS fans are expected to run for 20,000 hours ~ 40,000 hours in continuous operation. The higher
the ambient temperature, the shorter the fan life.
During the UPS operation, it is important to check the condition of the fans regularly by confirming that
they blow air out of the ventilation holes on the rear panel.
8.2 Battery Maintenance
NOTE: 1. Never invert the battery connections as this could result in fires.
2. Never attempt to open batteries since they contain electrolyte which is potentially harmful to
personnel. In the event of accidental with electrolyte, wash the affected area with abundant, clean
water, and seek medical assistance immediately.
The internal battery module of the UPS is sealed, lead-acid, maintenance-free battery. The battery life
depends on the ambient temperature, charge and discharge times. High ambient temperature and deep
discharge shortens the battery life.
To ensure the battery life, it is required to:
• Keep the ambient temperature ranging from 15 °C to 25 °C
• Prevent small current discharge. Continuous battery operation time exceeding 24 hours is
strictly prohibited
• Charge the battery for at least 12 hours, if the battery hasn’t been charged for three months at
specified ambient temperature, or two months at high ambient temperature
NOTE: 1. Check the battery connection screws are regular intervals, and re-tighten them if necessary.
2. Make sure that all the safety devices present, in good condition and that they function correctly, and
make sure that the battery management parameter settings are correct.
3. Measure and log the ambient temperature in the battery room.
4. Check whether the battery ports are damaged or hot, and check the condition of the chassis and the
covers.
If any of the batteries are found to be leaking, place them in a suitable container and dispose of them in
accordance with local regulations.
Lead-acid batteries are classified as hazardous waste material. The control of waste battery pollution is a
nationally important issue. Batteries must be stored, transported, used and disposed of in accordance with
national and local legal requirements and all other criteria applicable to the treatment of hazardous waste
material and waste battery pollution prevention.
