8. Maintenance
8.1 Preventive maintenance
The preventive maintenance of UPS system can ensure UPS reliability and
long-term service. The following inspections can be carried out every month.
1. Shut down UPS (specifically refer to operation steps).
2. Check the vent hole to ensure it is not blocked.
3. Check whether the cover has collected too much dust or not.
4. Check whether the input, output and battery cables are firm or not and whether
the cable insulation is good or not.
5. Ensure UPS is well protected against moisture.
6. Start UPS (specifically refer to startup operation).
7. Discharge UPS powered by the battery and other unimportant loads, until the
battery low voltage alarm sounds. During the period, there will be no other alarm.
If any other alarm is triggered, please contact local service center.
8.2 Battery maintenance
This machine adopts sealed lead-acid battery. The service life of the battery
depends on the storage and service environment and battery discharge frequency.
The temperature increase will shorten the service life of the battery rapidly. Even if
the battery is not used, its performance will decrease gradually. It is recommended
to carry out the discharge test once every three months in case of uninterrupted
power supply.
The checking methods of the battery will be introduced as below (the battery
performance will decrease sharply with the approaching of the expiration date, so
the following checking and maintenance methods shall be kept in mind)
1. Connect with the utility power line, start UPS, and charge the battery for more
than 8 hours. Pay attention to the operation condition of the loads connected to UPS.
