About Your New BayStack UPS45

This Uninterruptible Power Supply (UPS) is designed to prevent
blackouts, brownouts, sags and surges from reaching your
computer and other valuable electronic equipment. This UPS
also filters out small utility line fluctuations and isolates your
equipment from large disturbances by internally disconnecting
from the utility line, while supplying power from its internal
batteries until the utility line returns to safe levels.
While running on battery, an internal alarm will sound (periodic
beeps).
If the utility power does not return, the UPS will continue supplying
power to the connected equipment until exhausted. A continuous
beeping will sound two minutes before the UPS' s final low battery
shutdown. If using a computer, you must manually save your
files and power down before the UPS turns itself off.

Problem and
Possible Cause
Press the ON button once to power the
UPS and the load.
Check that the power cable from the UPS
to the power supply is securely connected
to the AC power source.
Reduce the load on the UPS by unplugging
equipment and reset the circuit breaker (on
back of UPS) by pressing the plunger back
in.
Check the AC power supply to the UPS
with a table lamp. If very dim, have the
utility voltage checked.
Confirm the battery connections according
to the BayStack UPS45 User' s Manual.

UPS and have it serviced immediately.
Reduce the load on the UPS by unplugging
equipment and reset the circuit breaker(on
back of UPS) by pressing the plunger back
in.
Move the UPS to a different outlet on a
different circuit.
None. The UPS is protecting the load.
Charge the battery. Batteries require
recharging after extended outages. Also,
they wear faster when put into service often
or when operated at elevated temperatures.
If the battery is near the end of its service
life, consider replacing the battery even if
the replace battery indicator is not yet lit.
Check the UPS' s load display. Unplug less
needed equipment, such as printers.
Do not attempt to use the UPS. Turn the
UPS off and have it serviced immediately.
Unplug less needed equipment, such as
printers.
Do another self test to see if it clears.
Confirm the battery connections according
to the BayStack UPS45 User' s Manual.
