There is no specific bracket per se, I think you need to get the HAI bracket which is around $20. Electron did this in his setup. Otoh, it is fairly easy to just mount the control like Spanky said.
My $.02 - the bracket is nice if you are not sure how you are laying out your panel as you simply unclip it and move it. If you know where the control is going in the panel and its not gonna move, just mount it by itself.
I did not use the bracket, and did wind up actually moving the controller, so I wound up just having to drill 2 extra holes, but I like it without the bracket and would personally save the money and put it toward something else.
fwiw, the control board sits in a plastic back box and has a snap on cover. To mount it, remove the cover (just pulls right off), take off the control board, use the back box as a template to drill your holes, put the control board and cover back on. Then drill the holes as marked, screw in the shoulder screws and slide the controller on it. Nice clean and simple...
