A SCF3 fault (fault 32 on the touchscreen) is a ground short circuit fault. This indicates that the system is not properly grounded. Verify that all wiring is correctly grounded on the input and output side of the VFD. Ensure that the cable is stripped properly so that the terminal is not biting on any insulation. You can also refer to SCF1 troubleshooting, as they are often related.
