Ensure that the mains input breaker (POWER), bypass breaker (BYPASS), output breaker (OUTPUT), maintenance
bypass breaker (MAINTENANCE) are all OFF.
Check load.
 Ensure that the load is not conductive load. The output of the UPS cannot be conductive load,
such as motor, fan, air-condition, etc. Generally, these loads are power supplied by power-grid.
 Ensure that the load is close. And at the same time, the load capacity should not exceed the UPS
rated output capacity, or, it will cause overload protection.
Ensure that there is no short-circuit between the live wire and neutral wire, live wire and grounding wire of input
and output.
Measure the AC voltage of mains input terminal (POWER), and the voltage should be within the range of 80V-
280V, or, it can be started from battery status only.
Measure the DC voltage of battery input terminal.The voltage of positive battery group should be greater than a
certain value (+11.5× battery amount), the voltage of negative battery group should be less than (-11.5× battery
amount), and pay attention to the polarity, avoid wrong battery connection.
Ensure that the auxiliary contact of battery breaker is connected to the ND4 dry contact of system monitor card at
front of the UPS.
2.3.2 Startup
Recheck all the system parameters setting and ensure that the setting is right.
Close the bypass breaker (BYPASS), ensure that the system bypass input is normal and with no output. The UPS is
initializing. After initializing, the system will turn to bypass power supply. Look up the system running status in the
touch screen, and ensure that the system is power supplied by bypass.
Start the inverter.
 Start the UPS by panel combination button.
Close the mains breaker (POWER).
30s later, long press the panel ON combination button for 3s, the system inverters to output. Check the
system running status in the touch screen, and ensure that the system turns to inverter from bypass
to supply power.
Click the output icon , inverter icon in the touch screen to look up the total output voltage,
output frequency and corresponding unit output voltage and output frequency and see if the voltage
is normal.
