The Inverter will stop operating or send out a warning signal when it detected a fault. The keypad
will show brief information of the trip and warning signal. If the model is using the LCD keypad, the
LCD will show detailed information.
The following is how the fault conditions are categorized.
• Level: After the fault is corrected, the trip or warning signal disappears. The fault is not saved
in the fault history.
• Latch: After the fault is corrected, the trip or warning signal disappears once the Inverter is
reset.
• Fatal: After the fault is corrected, the trip or warning signal disappears when conducted the
following procedure. Turn off the Inverter and wait until the charge indicator light goes off. Then,
turn on the Inverter. If the Inverter still failed, please contact the supplier or LSIS Customer
Service Center.
