3-3. Single UPS Operation
3-3-1. Turn on the UPS with utility power supply (to Line mode)
1)
Make sure mains input and battery are connected well, and the Battery pack breaker is at “ON” position;
Set the external mains input breaker to “ON” position, then the fan will be running and the UPS supplies
power to the loads via bypass; (The UPS is operating in Bypass mode.)
NOTE: When UPS is in Bypass mode, the output voltage comes directly from utility, so the load is not
protected by UPS. To protect the precious load, the UPS should be turned on to Line mode.
2)
When LCD is on home page, press the “ON/ENTER” button, LCD will show a prompt page of “Turn On”;
Move the arrow to “Yes” by up or down button, then press “ON/ENTER”, the UPS will be starting up with
beeping once. You could also enter the “control menu” to select the instruction “Turn On” to startup the
UPS. Please refer to the section of “LCD operation”.
3)
A few seconds later, the UPS will enter into Line mode; “Line mode” will be displayed on LCD. (In line
mode, if the utility power is abnormal, the UPS will transfer to Battery mode without interruption.)
3-3-2. Turn on the UPS without utility power supply (to Battery mode)
1) Make sure the battery is connected well and the Battery pack breaker is at “ON” position;
2) Press the “ON/ENTER” button to start up the internal power, the UPS will enter into bypass mode
without output;
3) When LCD is on home page, press the “ON/ENTER” button, LCD will show a prompt page of “Turn On”;
Move the arrow to “Yes” by up or down button, then press “ON/ENTER”, the UPS will be starting up with
beeping once. You could also enter the “control menu” to select the instruction “Turn On” to startup the
UPS. Please refer to the section of “LCD operation”.
4) A few seconds later, the UPS will enter into Battery mode; “Battery mode” will be displayed on LCD (In
Battery mode, it will shutdown automatically when battery is depleted. If the utility power is restored, it will
auto restart to Line mode.)
3-3-3. Connect devices to UPS
After the UPS is turned on, you can connect devices (load) to the UPS.
1) Turn on the UPS first and then switch on the devices one by one, the LCD panel will display total load
level;
2) If inductive loads needed to be connected, such as a printer, the in-rush current should be calculated
carefully to see if capacity of the UPS can cover due to the huge starting power consumption of this kind
of load;
3) If the UPS is overload, the buzzer will beep twice every second;
4) When the UPS is overload, please remove some loads immediately. It is recommended to have the total
loads connected to the UPS less than 80% of its nominal power capacity for system safety;
