6. Maintenance
6.1 Care and maintenance
To ensure a long service life of the system, the area around the UPS
system should be kept clean and free of dust. If the area around the
system is very dusty, clean the outer surfaces of the system using a
vacuum cleaner.
To ensure a long service life of the batteries, the ambient tempera-
ture should lie below 25°C.
NOTE

Make sure that the UPS system is switched off and discon-
nected from the mains power supply before transporting the
UPS system

However, the service life of a battery varies depending on
the frequency of use and ambient temperature. After expira-
tion of the expected service life, batteries which continue to
be used frequently have reduced running times. Exchange
the batteries regularly so that the system is always running at
optimum performance.
6.2 Storage
If you store the UPS system over a longer period of time, charge the
batteries every six months by connecting the UPS system to the
mains power supply. The internal batteries will charge up to 90% of
their capacity in less than three hours. ONLINE recommends charg-
ing the batteries for 48 hours after longer periods of storage (>3
months).
6.3 Proper time to change the battery
If the display lights up whilst the UPS system is running, the
batteries must be exchanged. Contact your dealer or ONLINE
(
