Very few VFDs are actually designed as single-phase input. They use three-phase rectifiers, but size the diodes and caps such that they can handle the additional stresses of running on single phase with only two of the three incoming wires connected. Consult the manual (assuming it is in a readable dialect of Chinglish) to find out how they want you to wire it.
In the absence of a manual, I'd probably connect one input to L1 and L3 (this runs the L1 and L3 diodes in parallel, you might as well use the silicon if it is there), and the other input to L2. Or just connect to L1 and L2, and ignore L3.
