The 4th wire won't be connected. Personally don't bother with an earth onto spindle has the VFD and main machine frame are earthed and VFD will shut down protecting it's self if detects short or heavy load. Just make sure the shielding is taken back to main earth point.
Big tip is to make sure the VFD connector terminals are soldered securely and no stray strands wires floating about and all wires are isolated well. Also that the wire is supported well so there's no stress on the connector. If not and the wire comes loose and shorts then it WILL more than likely KILL the spindle and possibly the VFD.? . . I've done this my self killing both spindle and VFD and know of others.!!
The wiring is easy. Just connect U V W If it spins reverse when first started just swap any 2 wires and it will spin right way.
