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.
Reduce load by removing the least
critical load items from the UPM
output.
Recharge battery for at least six
hours and reset the UPM. If LED is
still illuminated, replace the battery.
Contact a qualified electrician to
verify wiring at this site.
Recharge battery for at least six
hours and retest backup time.
Connect computer input power cord.
1. Purchase correct cable
2. Check to see that the port
is enabled in the CMOS
settings. Also check for
IRQ conflicts. Make sure
settings match those found
in Communications
Manager.
3. Replace I/O card
