Your spindle system, and ATC system comes with a mounting method as described in this video. 

As an alternative we have our VFD Mounting Brackets which will allow you to mount it whereever cables will go. 

The included hardware is only for a vertical orientation. 

Alternatively, if you would like to mount your VFD in an alternative orientation, or want easier access to attaching it to the desired surface, look into our Mounting Brackets
