2.Push button for manually triggering the system test or switching off the buzzer

3.Push button to view the configuration

4.Acknowledgement button

5.INPUT TYPE: LED for preselected operation state and output voltage

NORMAL: (Normal mode) The LED indicator will illuminate during normal mode, the UPS accepts AC input voltage range from +/-20%.

GENERATOR: (Generator mode) No change to voltage window. However, the low frequency transfer point is changed to 40Hz and there is no limitation for high frequency transfer point.

WIDE RANGE: (Extended UPS)

AC input voltage ranges from -30% / +20%.

6.VOLTAGE RANGE: LED for current output rate voltage 220Vac / 230Vac (ex factory) / 240Vac.

7.LINE MODE: Green LED for power mode. The line LED indicator illuminates when the AC source is present.

8.BAT. MODE: Yellow LED for battery mode. The LED indicator will flash every four seconds when the UPS
