
Note: The function of active power derating and
reactive power compensation is optional. For detailed
information, you may call our after-sales service center.
(2) “2 Restart” menu. If an internal fault shutdown
happens, a severe fault has occurred inside the inverter. The
user may perform a force restart once in this menu if the user
needs to restart the inverter.

Note: this function is effective only when the fault
“IntFaultA~O” in the troubleshooting table occurs.
The inverter may restore to normal operation
automatically if alarm or protection faults occur.
