6.3 Storage
6.3.1 STORAGE OF THE UPS
The UPS is carefully packed for transport and storage.
Never leave a UPS outside the building exposed to the elements and
do not
place
other packages on the top of the UPS.
Storing: It is recommended to store the UPS in its original package in a dry, dust-
free room, away from chemical substances, and with a temperature range of -25°C
(-13°F) to 55°C (131°F). Exceeding this temperature range may cause damage.
Important functions of the UPS, are defined by parameters stored in a RAM
memory. The RAM is supplied by a small backup battery located on the Controller
board. If the storage time of the UPS exceeds 1 year, these functions should be
verified
by an Always
O
n Service Center
before putting the UPS into operation.
6.3.2 STORAGE
OF
BATTERY
Although this system includes maintenance free batteries, keep in mind that they
are subject to self-discharge and therefore must be recharged.
The storage time without battery recharge depends on the temperature of the
storage site. The optimal temperature for battery storage is 20°C (68°F) to 25°C
(77°F).
Recharge of the stored maintenance free battery every:
6 months when the ambient storage temperature is 20°C (68°F)
3 months when the ambient storage temperature is 30°C (86°F)
2 months when the ambient storage temperature is 35°C (95°F)
