ETA Systems ® - SECURITY ONE UNINTERRUPTIBLE POWER MANAGER
The UPM is shipped with a charged battery, but some discharge naturally occurs during storage
and shipment. You may use the UPM immediately, but you should realize that backup time may
be less than the stated rating until the UPM battery has had at least six hours to charge.
ETA Systems recommends that you do not plug laser printers into the UPM.
Laser printers are known to draw large amounts of current when the
fuser/heater assembly is energized. Laser printers can easily overload the
UPM or create a low voltage condition that can interfere with the operation
of the Voltage Manager circuit.
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 3
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.
Note: This product is not designed for continuous use on batteries.
Troubleshooting
The troubleshooting information provided in this section should help you discover the cause of most
commonly encountered difficulties. Before following the troubleshooting steps provided, be certain that you
have verified the following items:
The UPM should be plugged into a properly working outlet.
The line voltage to the UPM is within specified boundaries.
The circuit breaker on the rear panel of the UPM has been reset.
The battery enable plug (s) is installed.
Problem Possible Cause
UPM does not power up 1. On/Off button is not pressed
and has no audible alarm long enough

voltage too high or too low
3. UPM input power cord is not
plugged in
4. Rear panel circuit breaker is
tripped
Action you should take
