5. Operation
5.1 Turn-ON
With the UPS connected to an A/C power source, 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. Where applicable verify the
circuit breaker on rear panel is 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 Turning Unit Off & Power Down
Press and hold the OFF button for more than one second. The 2000VA and 3000VA units require that
the rear panel breaker also be switched OFF to shut down entirely. 1000VA and 1500VA units require
input power cord to be removed from AC power source. The LCD panel displays “888.8” and the unit
will begin the power down process, which may take up to one minute.
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 “BACKUP” 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 “BACKUP” icon will turn
OFF and the “INV” icon will illuminate.
If the UPS fails the self-test, the unit will go into BYPASS mode & may display a fault code (see
Troubleshooting), the loads are not affected. Recharge the battery overnight and perform the self-test
again. If the the self test fails again, contact tech support.
5.4 Audible Alarm Silencing
To silence the audible alarm, press the “ON/TEST” button for more 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.
5.5 Load Bar Graph
The 5-segment display indicates the power drawn from the UPS by the load. The number of illuminated
segments represents the percentage of the UPS's rated capacity being utilized. For example, if two
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.)
NOTE: If the UPS is overloaded, the fault code “E04“ illuminates and an alarm sounds.
(See section 6)
5.6 Battery Charge Bar Graph
The 5-segment display shows the present charge of the UPS's battery as a percentage of the battery
capacity. When all 5 segments are illuminated, the battery is fully charged. When only 1 is illuminated
the battery can supply less than 5 minutes of run time for the load.
(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.
