26、ODUCTION The standards IEC 60297-3-100 and IEC 60917-2-1 for electronic cabinets have been established for systematically defined external dimensions and for the internal mounting dimensions of subracks and chassis considered as the most common mechanical designs of electronic equipment. Comparing t
27、he above two mentioned standards it becomes obvious that both follow the same metric footprint but differ with respect to the mounting dimensions for the installed equipment. Furthermore, there are no definitions in either standards for the interface dimensions of any other miscellaneous equipment.
28、This kind of equipment is primarily not designed to standardized mounting dimensions insofar as it is meant for subracks or chassis. The installation of such non-standard equipment into cabinets used to be accomplished by supporting shelves or special mounting devices. In addition to the above menti
29、oned lack of dimensional definitions there are many accessories for special applications where a definition of interface dimensions could facilitate the adaptation to a cabinet, e.g. internally or externally mounted cooling device and other miscellaneous devices. It seems worthwhile to create a stan
30、dard for modular cabinets with the definition of interface mounting planes and mounting points for internally and externally mounted miscellaneous devices. Such an attempt could fulfil the dimensional preconditions for an environmentally optimised modular structure, such as: definition of a frame-ba
31、sed cabinet structure for the individual combination of piece parts e.g. doors, side covers, top covers; interfaces for miscellaneous devices by definition of mounting planes with mounting points on the cabinet frame structure; mounting of equipment of the IEC 60297 and IEC 60917 series within the s
32、ame cabinet with associated mounting uprights; modularity of the frame-based structure supporting shipment in the form of kits in order to maximize logistics efficiency and to minimize costs. Legacy cabinets complying with IEC 60917-2-1 and IEC 60297-3-100 may be considered in conjunction with cabin
33、ets of IEC 60917-2-5 without significant technical modifications due to the fact that all follow the same coordination dimensions. Whilst the internal mounting points for mounting standardized equipment are defined in IEC 60297-3-100 and IEC 60917-2-1 in case of IEC 60917-2-5 additional mounting pla
34、nes and mounting points are defined to be used for attaching miscellaneous equipment or accessories.

Based on a 600 mm 600 mm cabinet, the external frame dimensions of cabinets, as sh
46、own in Figure 3 define the boundaries which shall be always within the pitch lines of the coordination dimensions. Doors, roofs, side and rear covers may stay within or exceed the pitch lines by. 25 mm, max as shown in Figure 3. Side covers exceeding the coordination dimensions may be used on single
47、 cabinets or at the end of a row of cabinets. For side by side mounted cabinets, the side covers mounted between the cabinets shall not exceed the pitch line.

48、et frame mounting points may be on any cross point of the 25 mm grid. The start points are on the cross points of the pitch lines of the external coordination dimensions as shown in Figure 3. The mounting points of a cabinet are, by definition of this standard, on the mounting planes of the cabinet
49、frame structure. The mounting points identify the location of the mounting holes for the attachment of internal and external equipment or accessories. The mounting points in Figure 3 are shown as a top view of a 600 mm wide and 600 mm deep cabinet frame. The same applies to all members of the cabinet frame. The figures used for the definition of mounting planes and mounting holes are not intended for purposes of physical design, but only for locating
