Hello all,
I have just purchased and received a new cnc from jinan omni in china. After looking over the cnc I found that it does not have a plug attached, so I can plug it in to my 220v. I have received some photos from omni showing how they have 220v hooked up to the terminals inside the control cabinet. after reviewing them, I am a bit confused. They have two hot wires no ground. I only know of a 3 prong plug for 220v here in the states. I have included the photos of their hook up, along with how I hooked up the 220v to my cabinet. Is the way I hooked up the 220v correct?

This is how I hooked mine up.

I was told the way I have it set up it will create static on the control cabinet when running.

Please help!
