Height unit markings on both mounting levels can be read from both inside and outside for simplified component installation. All height units are marked on the mounting angles and numbered in opposite directions. Mounting angles front and rear, material thickness 2.0 mm, with additional pitch pattern in accordance with the standard EIA 310 E.
Alternative mounting dimensions for 21", 23" or 24" components can also be realised. Imperial mounting levels can be positioned either symmetrically or asymmetrically with an offset to each other. Mounting levels comprising universal mounting angles, front and rear, depth-variable, 15 mm pitch pattern, screwed to depth stays of the enclosure frame at top and bottom. The total static load capacity of both mounting levels is 500 kg. Mounting levels: Enclosure pre-configured with two 482.6 mm (19") mounting levels, front and rear.
To support passive ventilation the cover plate can optionally be raised by using a spacer. concealed cut-out in the rear third to accommodate a fan unit for active ventilation. Roof plate: One-piece solid roof plate, screwed incl. Door hinge side can be swapped, door opening angle 135° for stand-alone enclosures, 105° with baying. Front and rear door with design handle and 2-point locking rod, security lock 3524 E, exchangeable for an AX comfort handle for optional integration of a profile half-cylinder. One-piece solid sheet steel door at the rear. Front and rear door: Glazed sheet steel door at the front, with 3 mm single-pane safety glass (ESG). Base: Open base frame, without gland plates, for optional individual configuration with base modules from the range of accessories. Enclosures can be bayed to the front and rear, as well as to the sides. The vertical frame sections each possess two mounting levels offset in the depth and width directions, which can be used individually for flexible mounting of the components. All frame sections with integrated system punching in a 25 mm pitch pattern permit convenient interior installation through simple attaching and fastening of the installation components. Rack frame: IT rack, comprising a torsionally rigid, welded and symmetrical frame of rolled, 16-fold vertical sections connected with a horizontal frame at the bottom and horizontal cross rails with welded roof plate at the top. IT rack, installation height 24 U, glazed sheet steel door at the front, one-piece solid sheet steel door at the rear.
