On Battery (yellow)

Utility power is outside accept-
able limits. The battery is powering

only the Battery Backup outlets. The expected
run-time for a typical personal computer (PC) is
19 minutes total.

Momentary Tone

-

a two (2) sec-

ond duration tone is sounded two
seconds after utility power loss has

occurred. The UPS will continue to run with-
out an audible alarm until a low battery condi-
tion is reached (see below).

Continuous Beeping

-

the UPS is

near the end of its battery runtime.

Promptly save your data and

all applications. Shutdown the operating
system.

The UPS beeps continuously (1-2

minutes) until it shuts down from battery
exhaustion or returns to On Line operation.

If power is outside acceptable limits, and the
optional software is installed, the host computer
signals the UPS to shutdown. In Shutdown
Mode, the UPS disconnects power to the Battery
Backup outlets to conserve battery capacity. The
On Line and Overload indicators flash alter-
nately for 20 seconds. When utility power is
restored, the UPS returns to On Line operation.

Surge Protection Outlet (1)

Connect a printer, fax machine, or scanner to
this white outlet. This outlet does not provide
power during a power outage.

This outlet is

always On (when utility power is available)
and is not controlled by the On/Off button.

• Do not connect a printer to any Battery

Backup outlet.

• Do not connect a surge suppressor, power

strip, or extension cord to the UPS.

outlet.

Do not power the UPS using a surge

suppressor or power strip

.

Battery Charging:

The UPS battery charges

whenever the UPS is connected to utility power
and typically requires less than five (5) hours to
charge fully. Operating runtime is reduced until
the battery is fully charged.
