2.2KW 220V 80mm installation. What is this part?

Hello, I’m almost done assembling my Onefinity Foreman Elite. The spindle installation is pretty straightforward, but there’s a black plastic piece in the box and I have no idea what it’s for. Here’s a pic.

Thanks for any input.

It is a french cleat. It is used for mounting your VFD to your table or whereever you wish to mount it. If you look at it there is an angled edge that fits into the back of the VFD. Mount the plate on your table with a couple of screws then hang the VFD on the plate. There is also a little clip that attached to the bottom of the VFD to keep you from knocking the VFD off the table.

Ahh, I see. That makes sense. Great idea.

Thanks!
