4. 2 Operation Mode
UPS Operation Mode contains normal mode, battery mode and bypass mode. Under the three modes, the
page showing output voltage and output frequency is the main display page. If users need more information
about UPS, Pressing the function button can initiate display screen switch. If the current page is not the main
page, UPS will automatically switch back the main page after 30 seconds. In order to extend the LCD usage
life, the backlight will turn off after
1 minute without any switch operation. At this point, Users just need to
touch any button briefly to turn on the backlight.
4.2.1 Normal mode
When operating in the normal mode, the display of main page on the front panel is shown as the figure 4-2.
The utility power indicator and the Inverter indicator are turned on. Load information area shows load value,
and the battery level area indicates dynamically when the battery is not fully charged (the battery level icons lit
one after another circularly). When the battery is fully charged, all the level icons are turned on.
1) If the utility power indicator blinks, it indicates that there are problems with reversed polarity (L, N) of site
wiring or disconnect with ground. UPS is still working in normal mode. If the battery indicator is turned on at
the same time, it shows that the voltage or frequency of the utility power is out of the normal input range of
the UPS. The UPS works in battery mode.
