Preventative Maintenance
Preventative Maintenance ensures the longer service life of UPS.
Please check the following things every month:
1. make sure the airway not blocked;
2. make sure that the UPS surface is not covered by dust;
3. Check whether the input, output and battery connecting lines are firm or not and the
insulation is effective or not;
4. Make sure that the UPS is not affected with damp;
5. Let the UPS work in battery mode for about 5 minutes and in this period, if there is no other
alarm from the UPS, then the UPS is normal; if there is other alarm message, please contact the
local dealer for help.
Battery maintenance
The UPS contains sealed lead-acid maintenance-free battery. The bad environment, high
discharging frequency, high temperature etc will dramatically reduce the service life of battery.
The service life of battery will also reduce even it is not used. It is suggested to discharge the
battery once every 3 months when AC is normal. When battery is near the end of its life, the
battery will end in bad performance.
