3.1 Operation
1. Turn on the UPS with utility power supplied (in Line mode/AC mode)
1) After you make sure that the power supply connection is correct, set the bypass
breaker and the input breaker in the “ON” position first. At this time the fan
rotates and the UPS supplies power to the load via the bypass. The UPS operates
in Bypass mode.
2) Then power on the UPS by simply pressing the “ON” button continuously for more
than one second. When being powered on, the UPS will perform self-diagnosis,
with the load/battery level LEDs turned on and then off one after another in
ascending order. A few seconds later, the INV LED is turned on, the UPS is
already running in Utility Power mode. If the utility power is abnormal, the UPS will
operate in battery mode without output interruption of the UPS.
2. Turn on the UPS with no utility power supplied (in Battery mode)
1) Press the “ON” button continuously for more than one second to power on the
UPS. For long back up time model (“XL” model), please make sure that the
battery breaker is in “ON” position.
2) During the course of starting up, the UPS has the same action as if it is connected
to utility power except that the utility power LED is not turned on but the battery
LED is turned on instead.
3. Turn off the UPS with utility power supplied (in Line mode/AC mode)
1) Press the “OFF” button continuously for more than 1 second to turn off the inverter
of the UPS immediately.
2) When being powered off, the UPS will perform self-diagnosis, the Load/Battery
level LEDs will be turned on and then off one after another in ascending order,
then the INV LED will be turned off and Bypass LED will be turned on. The UPS is
working in Bypass mode.
3) Upon completion of the above to turn it off, output of electric current of the UPS is
still present. In order to cut off the output from the UPS, simply cut off the utility
power supply and the UPS will perform self-diagnosis, finally no any display is
shown on the display panel and no voltage output is available from the UPS
output.
