The Rack Mounting Shelf (CS0449) provides a simple solution for installing controllers to the 19” rack. It allows to the installation of up to two half-rack-sized controllers to a single 19” unit rack space. All necessary accessories are supplied with the shelf.

The controller is fixed to the Rack Mounting Shelf by two screws M3 x 6 using female threads on the bottom side of the controller - see picture below. Screws M3 x 6 are bundled with Rack Mounting Shelf. Don’t use longer screws to avoid damage to PCBs inside the unit. If you install only one controller use the cover panel delivered with the shelf.

If you install less controllers, use cover panels delivered with the shelf to cover empty positions.
