Storage
The UPM may be stored for extended periods in an environment that does
not subject the UPM to extremes of temperature or humidity. When storing
for extended periods, the battery should be charged every six months. If the
storage location is characterized by above normal temperature, the battery
should be recharged every two months. The UPM does not need to be
turned on for charging to occur – it only needs to be plugged in with batteries
connected.
NOTE:
This product is not designed for continuous use on batteries.
Attention
Important Information
The batteries inside this UPM are a special type called “sealed lead-acid”.
These batteries use a non-liquid electrolyte, which makes it possible to
use them in any physical orientation. The batteries are designed to last
from two to ve years. Their actual life span will depend on several factors
including how often power outages occur, how long power outages last,
and the temperature of the environment in which the UPM operates.
Frequent, long duration power outages will shorten battery life more
than infrequent, short duration outages. Consistent high temperatures
in the area where the UPM is used will also shorten battery life.
The UPM is equipped with a Low/Replace Battery LED ( ) on the front
panel. If the LED illuminates, you should make sure that the battery has at
least six hours to charge without a power interruption. Inadequate (much
shorter than usual) backup time, premature low battery alarm sounds, and
persistent Low/Replace Battery LED illumination are all good signs that the
batteries inside your UPM requires replacement. The batteries inside your
UPM are designed to be replaced by an authorized service personnel only.
