Maintenance
8.1
UPS Cleaning
Before starting any cleaning operation, be sure that:
1.
The AC Input Voltage for the UPS has been removed.
2.
The UPS is OFF.
Use only a cloth dampened with water to clean the unit.
If UPS works in an environmental unusually dusty or dirty, remove the dirty from the ventilation holes.
Before restarting the UPS be sure it is completely dry. If any liquid gets inside the UPS, do not start the unit and
contact Technical Service immediately.
8.2
Battery
If the UPS is NOT going to be used for a long period of time, ensure that the batteries are left fully charged.
If the UPS has not been used for more than three months, go through the “First Start Up” procedure described in
the chapter 5 before using it again.
Please keep in mind that the batteries must be recharged at least once a month. Take in mind that batteries are
recharged automatically if the UPS works in Normal mode or if the UPS is off and connected to the AC Input Line.
Battery life strongly depends on the ambient temperature. There are also other factors like the number of charge-
discharge cycles, the discharge depth, humidity and altitude.
The recommended environmental specifications for a correct use of batteries are listed in the “Technical
Specifications” section.
