Hey David,
thank you for providing this information and images!
What we can see here is confusing but does not surprise me.
It is clear that installing, wiring, programming and using such a complicated device like a VFD witout documentation would be a challenge. I would try to find a manual. But you might find none as I would consider this as a no-name VFD with stolen Huanyang model description; a counterfeit.
Also the data on your nameplate seem to be pure fantasy. You will hardly get 10 A output when drawing 7.5 A input on one phase input. See also
Here you can see my VFD’s nameplate:
It is a VFD for 2.2 kW spindle for one-phase 200-V-class input.
As you see, it says it will draw 24 A on single phase input to deliver 12 A three-phase current. That is realistical. A VFD is a AC-to-DC-to-AC inverter.
Glad that my VFD has a very good manual 
. I buy my CNC stuff at a CNC parts supplier.
