ETA SYSTEMS - UNINTERRUPTIBLE POWER MANAGER
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 2 to 5 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 battery inside your UPM requires replacement. The batteries
inside your UPM are designed to be easily replaced by a user who possesses basic mechanical/electrical
knowledge and simple tools. Please familiarize yourself with the following precautions before proceeding
with battery replacement.
WARNING !!
Servicing of batteries should always be performed or supervised by
someone who has read and understood the following precautions and who
understands the hazards associated with storage batteries. This procedure
should not be performed by someone who is unauthorized or who is
incapable of following these precautions.
OBSERVE THE FOLLOWING CAUTIONS
Only the battery assembly in this unit is user serviceable. The battery compartment is
accessed by removing the front panel as described in the following instructions. No
other user serviceable parts are contained in this UPM. Do not remove any cover
other than the front battery access panels.
A battery (even a depleted one) can deliver very high currents when short-circuited.
There is a danger of electrical shock. Remove all watches, rings, bracelets or other
metal objects. Use only tools with insulated handles.
