Overview
This standard specifies alternative dimensions and features for subracks and associated plug-in units which differ in certain parts of IEC 60297-3-101. These alternatives allow more sturdy designs for the load bearing members of the subracks. In addition, the plug-in units are equipped with alignment pins and fastened with M3 screws. The main differences concern the injecting and extracting provisions for plug-in units and the decrease of the subrack height aperture in order to increase the dimension for the top and bottom members (most critical load bearing parts). The mounting flanges of the subracks are recessable. This feature meets the mounting requirements of heavy subracks and allows the positioning to the centre of gravity. The responsible committee is DKE/K 662 "Bauweisen" ("Mechanical structures") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
