I have the VEVOR SY-1.5HP-2P-B34-C and am using American system having two phases A and B, both 115V, a Neutral line (0V) and a Ground. Your wiring diagram shows Line 1, Line 2, and INS. for a 230V connection. For a 115V connection, it shows only Line 1 and Line 2. 2 phases (phase to phase) will make 208V, so I don't think this is the intended connection. What do Line 1 and Line 2 connect to in the 115V diagram? Perhaps I should have purchased a 2-phase motor instead?
