Terry you can put Live and Neutral to any of the R, S, T doesn't matter which way around it will work. I just use R & S

UVW is for the Spindle. Again doesn't matter which order you put wires it will work, however, if the spindle spins the wrong way when Forward direction is selected then swap any two wires and it spin correct direction.

AndyUK, Starting VFD without Spindle connected won't hurt it. Even connecting spindle wires with VFD turn on won't hurt it PROVIDED the spindles not set to RUN. However I wouldn't be recommended so always turn off.
