sound (as a continuous tone) regardless of the position of this switch. This
means that there is about 2 minutes of backup time left (at full load.)
(8) Plug the power cord back into the AC outlet. The AC ON light will
come back on and after a few seconds, the INV ON light will go off. The
UPS has just made a transfer from inverter back to AC. All your equipment
should continue to operate without interruption.
(9) If the power outage had been real and prolonged, the UPS may have
shut off due to low battery voltage. If AC power returns, the UPS will
resume normal operation and charge the batteries. Turning the power switch
off and on again will restart the UPS regardless of battery voltage or AC
power condition.
(10) In some rare cases you may find that after leaving the UPS unattended
for a power outage lasting several days, the UPS will not turn on and operate
even after AC power returns. This is because the protection circuitry has
activated to prevent damage to the batteries. To restart the UPS, first make
sure that the UPS is plugged in to an AC outlet and that the green AC ON
light is on. Next, turn off the UPS and leave it off for at least 5 minutes.
Now turn the UPS on again. The UPS should come back on and the
batteries will begin to recharge. Allow the batteries to recharge for at least 24
hours.
(11) When an overload occurs and the UPS shuts off, you must remove the
excess load and reset the UPS by turning it off and then on, before the UPS
will resume proper operation.

Your UPS will hold up a typical
desktop PC for about 10 to 20
minutes during a power outage.
However, as the batteries inside
your UPS get older, your holdup
times will go down. You may wish
to test your UPS about twice a year
to prevent against battery failure.
¨
Hint: Your UPS can self-start, i.e.
start providing AC power even
when there is no utility AC power.
Just turn on the Power Switch.
Your UPS can communicate with a network file server, UNIX workstation or
a PC using the alarm interface port. This port provides functions compatible
with Novell, Windows 3.1/95/NT, Vines, 3COM, Lantastic, AppleShare and
other network operating systems. With the proper software and interface
cable, your file server can warn users of a power failure and, if necessary, shut
down safely and automatically. For network installation, please refer to the
instructions accompanying the software and your network documentation.
