Guys need help with a Chinese spindle and VFD I bought (110V 2.2KW) yes I know weak combo but that is what I bought.


The instructions provided by Huanyang say to connect pins 1,2,3 from the spindle to the VDF and makes no mention of #4 which is I think is the ground.

Also the VFD instruction sheet makes a mention to its #9 pin which is earth but does not indicate where to connect it to or any connections to it.

I had purchased a power cord from home depot (2 conductors) but I am going to be sacrificing one of my PC power cords (3 conductors) for this since it is a shielded power cord. Once I get a 3 conductor wire, I Am not sure if the earth wire needs to go to #9 on the VDF or the S.

Any help would be appreciated.
Last but not least there are tons of variation on the internet and some event mention opening my spindle and making sure the ground wire is shorted to the spindle body since it is not from the factory... ????*??
