TURNING THE UNIT ON/OFF
ON / OFF / Test Button
SELF TEST
Press and release the ON/OFF/Test Button after one beep to turn the UPS ON
and supply power to the load. The load is immediately powered while the UPS
runs a two-second self test. Press and release the ON/OFF/Test Button after
one beep to turn the UPS OFF. The UPS will continue to charge the batteries
whenever it is plugged into an AC outlet and there is AC present.
The self test feature is useful to verify the correct operation of the UPS and the
condition of the batteries. With the UPS in the normal On-Line mode, press
and hold the ON/OFF/Test Button for approximately 4 seconds (four beeps),
then release the button. The UPS will perform a ten-second self test. During
the self test, the UPS will switch to battery power and the On-Battery LED will
blink and the audible alarm will sound. The length of the test that is automati-
cally performed every two weeks is longer than the start-up or user invoked
test. This test will run for approximately fifteen-seconds to measure the battery’s
capability to provide an acceptable amount of runtime. If the UPS fails a self
test, one of the LEDs will remain illuminated indicating the type of problem.
Note: The UPS will automatically perform a self test on start-up and every two
weeks.
DIP SWITCH SETTINGS
The DIP Switch setting may be changed by the user to set the desired Inverter
(on battery) output voltage and the Low voltage transfer set points. The DIP
Switches must be set to the desired Inverter output voltage and the Low voltage
transfer set points then, the UPS must be turned OFF and restarted to reconfigure
the microprocessor and save the changes. The Inverter (on battery) output
voltage setting can be either 120VAC (default) or 127VAC. Changing the In-
verter output voltage to 127VAC, will also change the Overvoltage set point from
132VAC (default) to 140VAC. The Low voltage transfer set points can be changed
to 85VAC (default) or 80VAC or 75VAC.
