NOTE!
When UPS is in Bypass mode, the output voltage will be directed from mains
after you switch on the input breaker. In Bypass mode, the load is not protected
by the UPS. To protect your precious devices, you should turn on the UPS. Refer
to next step.
2) Press and hold the "ON" button for 0.5s to turn on the UPS and the
buzzer will sound once.
3) In just a few seconds, the UPS will enter into AC mode. If the mains
is abnormal, the UPS will operate in Battery mode without interruption.
NOTE!
When the UPS runs out battery, it will shut down automatically in Battery
mode. When the mains is normalized, the UPS will auto restart in AC mode.
2. Turn on the UPS without utility power supply (in Battery mode)
1) Make sure that the two strings of batteries are connected correctly
in order of "+,GND,-" terminals and the breaker of the battery pack is at
"ON" position.
2) Press the "ON" button to set up the power supply for the UPS. UPS
will enter to power on mode. After initialization, UPS will enter to "No
Output mode", then press and hold the "ON" button for 0.5s to turn on the
UPS, and the buzzer will sound once.

3. Connect devices to UPS
After the UPS is turned on, you can connect devices 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 it is necessary to connect the inductive loads such as a printer,
the in-rush current of the load should be calculated carefully to see if it
meets the overload capability of the UPS. If connected load is more than
150% of designed capacity, the runtime will be less than 60ms.
3) If the UPS is overload, the buzzer will beep twice every second.
