I've posted this question in the DIY area, but I realize it might be more appropriate here.

I recently purchased a spindle/VFD combo and the inverter manual is in Chinese. This is a 2.2kW spindle and the VFD will take 220V single phase and produce 220V three phase at up to 400 Hz.
I'm concerned that I don't even have enough information to turn this over to my electrician, or that I'll be able to work through the setup and basic functionality once the wiring is done.
Even so, I may continue to plod ahead but would like some help with understanding the wiring diagram. The seller has informed me that the inputs/outputs look like this:
1) R (L) to 110V single phase
2) S to 110V single phase
3) T (N) to neutral (???)
4) P+
5) PR
6) U to motor pin 1
7) V to motor pin 2
8) W to motor pin 3
9) E to ground
I've gotten some good advice from 123CNC, but did not think there was any neutral connection. This seems consistent with other 2.2kW VFDs.
Has anyone successfully wired/operated one of these units? I'm on the verge of returning it and would find someone who has one working before I punt. Is it time for a Hitachi X200?
Thanks,
Steve
