Note: Check the wiring is correct, close the circuit breaker, the inverter power, press the
forward button for 1-2 seconds and then stop, check the pump running direction, if the direction is
reversed, then change the motor wiring phase sequence

If the inverter is in hibernation mode
and the current running command is
valid, when the setting frequency is
greater than or equal to the wake-up
frequency of F7.46, the inverter will
start to start after the delay time of
