INSTALL SOFTWARE ON

There are four status indicators (lights) on the front
panel of the Back-UPS (On Line, On Battery, Overload,
and Replace Battery).
On Line (green) - is lit whenever utility power is
powering the Battery Backup outlets.
On Battery (yellow) - is lit whenever the battery of
the Back-UPS is powering equipment connected to the
Battery Backup Outlets.
Four Beeps Every 30 Seconds - this alarm is
sounded whenever the Back-UPS is running On
Battery. Consider saving work in progress.
Overload (red) - is lit whenever power demand has
exceeded the capacity of the Back-UPS.
Continuous Tone - this alarm is sounded
whenever the Battery Backup outlets are
overloaded.
Circuit Breaker - the circuit breaker button
located on the rear panel of the Back-UPS will
stick out if an overload condition forces the Back-
UPS to disconnect itself from utility power. If the
button sticks out, disconnect non-essential
equipment. Reset the circuit breaker by pushing
the button inward.
Replace Battery (red) - is lit whenever the battery is
near the end of its useful life, or if the battery is not con-
nected (see above). A battery that is near the end of its use-
ful life has insufficient run-time and should be replaced.
Chirps for 1 Minute Every 5 Hours - this
alarm is sounded whenever the battery has failed
the automatic diagnostic test.
Note: Allow the Back-UPS to charge for a full eight (8)
hours prior to use.
Press the front panel Power ON/OFF switch and observe
that the following events occur after pressing and
releasing the switch:
• The green On Line indicator flashes.
• The yellow On Battery indicator lights while
a Self-Test is being performed.
• When Self-Test has successfully completed,
only the green On Line indicator will be lit.
• If the internal battery cartridge is not
connected (see Step 1 above), the green On
Line indicator and red Replace Battery
indicators will light. The Back-UPS will also
emit a chirping sound.
Continuous Beeping - this alarm is sounded
whenever a low battery condition is reached.
Battery run-time is very low. Promptly save any
work in progress and exit all open applications.
Shutdown the operating system, computer and
the Back-UPS.
NOTE: Macintosh Users - for full USB performance,
use OS 9.22 or higher.
If Autoplay is not enabled on the computer, proceed
as follows:
1. On the computer desktop of the display, double-
click on My Computer.
2. Double-click on the CD-ROM drive icon and
follow the on-screen instructions.
If the rear panel Building Wiring Fault (red)
indicator is lit, a potential shock hazard exists
due to one of the following conditions:
• Open or high resistance ground
• Hot or neutral polarity reversed
• Overloaded neutral circuit
Improper building wiring should be
corrected by a qualified electrician. Do not
use the Back-UPS until the condition that
caused the fault is corrected.
Note: Improper building wiring will not
prevent the Back-UPS from operating, but it
will limit its protection capability.
