Maintenance
This chapter focuses on the UPS maintenance, including the fan maintenance, battery
maintenance, UPS cleaning, UPS state check, UPS function check.
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.
7.1
Fan Maintenance
In order to avoid injury or damaging the device, wait until the fan is completely
stationary before in-serting fingers or any tools into it.
The UPS fans are expected to run for 20000 hours ~ 40000 hours continuously. The higher
the ambient temperature, the shorter the fan life is.
During the UPS operation, please verify the fan status once every half year by confirming
that air blows out from the ventilation holes on the rear panel.
7.2
Battery Maintenance
1. Never reverse-connect the battery connections, otherwise the fire will occure.
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 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
