7. Maintenance
This UPS does not require any maintenance by the user except when the batteries wear out and must
be replaced.
The typical lifetime of a battery is 4 years at a room temperature of 25 °C, although this will also
depend on the working conditions.
Regularly check the unit’s residual capacity time to ensure that it is sufficient, at least once
every 12 months.
7.1 Storage
For long time storage in moderate climates, the batteries should be charged 6 hours every three
months. Repeat it every two months in high temperature locations.
The recharging procedure is described below:
Connect the UPS to a grounded outlet.
Unplug the unit after 6 hours.
Note the charge date, preferably by marking the packing in the area reserved for this purpose.
7.2 Cleaning
Before cleaning, you should switch off the UPS and pull the plug out of the socket after dis-
connecting the load.
Do not use scouring powder, aggressive detergents or spray cleaners to clean the UPS.
Be particularly careful not to block vents.
