Place the vfd in a vented box.
Built a frame that uses existing bolts for chip tray.
Added a foot bar that activates the stop function.
Vent holes on bottom of the housing that is below and in center so very safe.

I spent considerable time and expense enclosing the VFD for my South Bend 13" lathe in a fan cooled metal enclosure. I have been considering just mounting the VFD for my mill up and out of the way (I currently run it on a RPC). Your post confirmed for me that the work and expense of an enclosure is a good investment.
Sorry to hear about your melt down!

I made sure to locate the lathe VFD enclosure well above the headstock, to prevent chip entry.
The VFD on my PM mill is located well off on the left side ... but I think I might have to cover the openings (shown in the second photo of my previous post) with some tape, to be absolutely sure that no chips get in.

Converting a knee mill to 3phase/VFD
I've recently bought a Precision Matthews PM-835S. Advertised as a "small" knee mill, it's still amazingly massive - and TALL. I've had to build a platform to stand on (re-using some of the the 2x4s and OSB the mill was crated with), just to be able to reach some of the controls and levers...

I built my VFD enclosure with an input fan on the bottom and an output fan on top. Both have filters in place over the fans.
The input fan on the bottom has a higher cfm rating than the output, to maintain positive pressure inside the enclosure.
An added benefit of this setup is that you never have to clean the inside of the enclosure.
My theory with this design was that any chips small enough to pass through that filter gets pushed away by the air outflow. Big chips just land on the filter and get shop vac'ed off later.
It seems to be working. After 2 years of use, there isn't a spec of dust inside.
I would have put the fans on the sides, but the vertical fins on the Teco L510 heatsink work better with air flowing vertically through the fins.

I would never put a vent on top of an enclosure in a shop environment.
I recently added a VFD and a power supply to my Sharp mill. The exhaust is on the front of the cabinet but not facing toward the mill. I designed the louvered cover, and 3D printed it. The intake is on the back side of the mill, also protected by a 3D-printed fan guard.
