Chapter 12: Maintenance
12.1 UPS
UPS Cleaning
Regularly clean the UPS, especially the slits and openings, to ensure that the air freely flows into
the UPS to avoid overheating. If necessary, use an air blower to clean the slits and openings, and
clean and replace the filters regularly to prevent any object from blocking or covering these areas.
UPS Regular Inspection
Regularly check the UPS every half year and inspect:
1. Whether the UPS, LEDs, and alarm function are operating normally.
2. Whether the battery voltage is normal. If the battery voltage is too high or too low, find the
root cause.
12.2 Batteries
The UPS uses lead-acid batteries. Make sure to replace the batteries according to battery life. The
actual battery life depends on the environment temperature, usage, and charging/ discharging
frequency. High temperature and high charging/ discharging frequency will quickly shorten the battery
life; thus, battery inspection and maintenance are required periodically. Please follow the suggestions
below to ensure normal battery life.
Keep the usage temperature at 20 ~ 25°C (68 ~ 77°F).
Idle batteries must be fully recharged every three months if the UPS needs to be stored for an
extended period of time. Please fully charge the batteries until the battery percentage shown on
the UPS’s LCD is 100%

.
NOTE:
If the UPS’s batteries need to be replaced, please contact qualified service personnel.
During battery replacement, the loads connected to the UPS will not be protected if input
power fails.
12.3 Fans
Higher temperatures shorten fan life. When the UPS is running, please check if each fan works
normally and make sure if the ventilation air can move freely around and through the UPS. If not,
contact service personnel to replace the fans.
NOTE:
Please ask your local dealer or customer service for more maintenance information. Do not
perform maintenance if you are not trained for it.
