5.3 Self-Test
Use the self-test to verify both the operation of the UPS and the condition of the battery. To
perform the self-test, press the ON/TEST button more for more than 1 second, but less than 2
seconds, under normal power conditions. During the self-test, the UPS will operate in back-up mode.
NOTE: During the self-test, the load(s) use battery energy. The “ON BATTERY” LED or BACKUP
LCD icon will illuminate indicating the UPS is supplying power.
If the UPS passes the self-test, it will return to normal on-line operation. The “ON BATTERY” LED
or BACKUP LCD icon will turn OFF and the “ON LINE” LED or INV LCD icon will illuminate.
If the UPS fails the self-test, it immediately returns to on-line operation and the “REPLACE
BATTERY” LED or LCD error code will illuminate, however the loads are not affected. Recharge
the battery overnight and perform the self-test again. If the “REPLACE BATTERY” LED or LCD
error code is still illuminated, call tech support for battery replacement instructions.
5.4 Audible Alarm Silencing
To silence the audible alarm, press the “ON/TEST” button for less than one second while the UPS is
in back-up mode.
NOTE: This function will not work when the UPS is under “Low Battery” or “Overload” conditions.
NOTE: In back-up mode, the UPS will automatically turn OFF if none of the connected loads are active.
5.5 Load Bar Graph
The 5 LED or LCD segment display indicates the power drawn from the UPS by the load. The
number of illuminated LEDs or segments represents the percentage of the UPS's rated capacity
being utilized. For example, if two LEDs or segments are illuminated, the load is drawing between
20% and 40% of the UPS's rated capacity. (See section 3 for location of the display on the front panel)
If the UPS is overloaded, the “OVERLOAD” LED or LCD error code illuminates and an alarm sounds.
5.6 Battery Charge Bar Graph
The 5 LED or LCD segment display shows the present charge of the UPS's battery as a percentage
of the battery capacity. When all 5 LEDs or segments are illuminated, the battery is fully charged.
(see section 3 for location of the display on the front panel).
5.7 Cold Start
When the UPS is OFF and there is no utility power available or present, the cold start feature can be
used to apply power to the loads from the UPS using the battery as the power source. Press the
ON/TEST button until the UPS beeps and powers up.
5.8 Shutdown Mode
In this mode, the UPS ceases supplying power to the load after battery depletion while waiting for
the return of utility power. If utility power is not restored, an external device, such as a server with
the included software connected to the UPS via the RS-232 interface, can command the UPS to shut
down. This is typically done to preserve battery capacity after the proper shutdown of protected loads.

5. Operation
5.1 Turn-ON
With the UPS plugged in, press the ON/TEST button more than 2 seconds to energize the UPS. It
will perform a self-test each time it is switched ON.
NOTE: When switched OFF, the UPS will maintain and continue to charge the battery and also
respond to commands received through the computer interface port.
5.2 Turn-OFF
Press and hold the OFF button until the “LINE NORMAL” or “BACKUP” LED turns OFF.
