I am putting together my first CNC, but need help with the wiring for the control box for the VFD to make sure it will work and I don't blow my self up...

This will be coming from 240v (30amp) 1 phase power (L6-30P connector).
Note: Since the pins from the connector are 120,120, ground - I made the layout according

Can anyone offer any assistance or guidance?

I have included the diagram and the PDF I made

Thank You,

Steve

Ger,
Good point on the fuses, i was just being over careful as I have never wired anything up like this.. I will have to look at the booklet on the VFD to see what input I could use.

Does everything else look good, so I don't blow myself up?

Thank you to all for the advice and great pointers....
With regards to the E-Stop I thought of having 2 of them, one on the VFD cabinet (either connected directly to the VFD if I can or to a relay that sends power to the VFD)

I am in the process of waiting for parts to show up (Avid CNC parts, doing my own frame from 8020 heavy).

- Water cooled 2.2 kw spindle and VFD (I feel very comfortable with water cooling done high end computers with it for over 10 years)

For the control and motors still trying to decide but was leaning to Nema 34 size Teknic ClearPath CPM-SDK-3421S-ELN as I may want to extend this from a 4x4 to a 4x8 and kind of torn between the Masso and Centroid Acron.

This is really going to be a hobby for now, but with retirement not that far away, I may be more serous about it to keep me busy.

Open to idea's and thoughts..

Thanks Again,

Steve
