Abstract
Abstract A control cabinet with a rack composed of a plurality of horizontal and vertical frame pieces, enclosed by a plurality of wall elements and a cabinet door, where a mounting plate, which has sliders with guide receptacles on their undersides, can be fastened parallel to a rear wall element. Each frame piece has two adjacent sides which are disposed perpendicularly to each other and have identical rows of fastening receivers. The two adjacent sides of each frame piece form an inner edge oriented towards an interior of the control cabinet. At least one of the horizontal frame pieces comprises a depth brace and a guide rail with a guide bar disposed parallel to the depth brace. In the course of inserting the mounting plate into the rack the guide receptacles of the sliders receive the guide bars of the guide rails and the sliders are displaceable on the guide bars. The expense for parts and assembly for guiding the mounting plate is reduced without impairing the fastening possibilities on the rack where the guide rails with their guide bars are formed as one piece with the depth braces, and where horizontal inner edges of the depth braces abut against the vertical inner edges of the vertical frame pieces at a vertical distance to the horizontal inner edges of the horizontal frame pieces.
