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
In the normal mode, the display on the front panel is shown in the following diagram. The utility power
indicator and the Inverter indicator are turned on. The load/battery capacity indicator will be turned on in
accordance with the load capacity connected.
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 that may result in shock hazard. UPS
is still working in normal mode. If the battery indicator is
turned on at the same time, it shows that the voltage or fre-
quency of the utility power is out of the normal input range
of the UPS. The UPS works in battery mode.
2. If output overloaded, the load level indicators will be
turned on and alarm will beep every second. You should get
rid of some unnecessary loads one by one to decrease the
loads connected to the UPS less than 100% capacity of the
UPS.
3. If the battery indicator blinks, it indicates that no battery
is connected to the UPS or battery voltage is too low. You
should check if battery is properly connected to the UPS, and
press function button more than 2 seconds to start the battery
self-diagnosis. If the connection between battery and UPS is
confirmed without any problem, it may be due to the defect
or aging of the battery, please refer to the “troubleshooting”
in chapter 7 to solve the problem accordingly.
Note: Connection to the power generator should be made according to the following steps:
• Activate the power generator and wait until the operation is stable before connecting the output of the
power generator to the UPS (be sure that the UPS is in idle mode). Then, turn on the UPS according to the
startup procedure. After the UPS is turned on, the loads are connected one by one.
• It recommended that the capacity of the AC generator chosen should double that of the UPS.
4.2.2 Battery Mode
When operating in the battery mode, the display of main page on the front panel is shown as the figure 5-3.
The battery indicator and the Inverter indicator areturned on. If the utility power indicator blinks at the same
time, it shows that the utility power is abnormal.Load information area shows load value, and bat level area
shows current battery capacity.
