25、tion dimensions for the 25 mm equipment practice Cabinet interface dimensions for miscellaneous equipment FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical committees (IEC National Committees). The
26、 object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifi
27、cations (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental and non-governmental organizations l
28、iaising with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between the two organizations. 2) The formal decisions or agreements of IEC on technical matters exp
29、ress, as nearly as possible, an international consensus of opinion on the relevant subjects since each technical committee has representation from all interested IEC National Committees. 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Commi
30、ttees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any misinterpretation by any end user. 4) In order to promote international uniformity, IEC Nation
31、al Committees undertake to apply IEC Publications transparently to the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter. 5) IEC itself does n
32、ot provide any attestation of conformity. Independent certification bodies provide conformity assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by independent certification bodies. 6) All users should ensure that they have
33、the latest edition of this publication. 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and members of its technical committees and IEC National Committees for any personal injury, property damage or other damage of any nature whatsoev
34、er, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications. 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publicatio
35、ns is indispensable for the correct application of this publication. 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights. IEC shall not be held responsible for identifying any or all such patent rights. International Standard
36、 IEC 60917-2-5 has been prepared by subcommittee 48D: Mechanical structures for electronic equipment, of IEC technical committee 48: Electromechanical components and mechanical structures for electronic equipment. The text of this standard is based on the following documents: FDIS Report on voting 4
37、8D/509/FDIS 48D/516/RVD Full information on the voting for the approval of this standard can be found in the report on voting indicated in the above table. This publication has been drafted in accordance with the ISO/IEC Directives, Part 2. 4 60917-2-5 IEC:2012 A list of all the parts in the IEC 609
38、17 series, published under the general title Modular order for the development of mechanical structures for electronic equipment practices can be found on the IEC website. The committee has decided that the contents of this publication will remain unchanged until the stability date indicated on the
39、IEC web site under “http:/webstore.iec.ch“ in the data related to the specific publication. At this date, the publication will be reconfirmed, withdrawn, replaced by a revised edition, or amended. IMPORTANT The colour inside logo on the cover page of this publication indicates that it contains colou

Users should therefore print this document using a colour printer. 60917-2-5 IEC:2012 5 INTRODUCTION The standards IEC 60297-3-100 and IEC 60917-2-1 for electronic cabinets have been established for systematically de
41、fined external dimensions and for the internal mounting dimensions of subracks and chassis considered as the most common mechanical designs of electronic equipment. Comparing the above two mentioned standards it becomes obvious that both follow the same metric footprint but differ with respect to th
42、e mounting dimensions for the installed equipment. Furthermore, there are no definitions in either standards for the interface dimensions of any other miscellaneous equipment. This kind of equipment is primarily not designed to standardized mounting dimensions insofar as it is meant for subracks or
43、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 mentioned lack of dimensional definitions there are many accessories for special applications where a definition of interface dim
44、ensions 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 standard for modular cabinets with the definition of interface mounting planes and mounting points for internally and externally
45、 mounted miscellaneous devices. Such an attempt could fulfil the dimensional preconditions for an environmentally optimised modular structure, such as: definition of a frame-based cabinet structure for the individual combination of piece parts e.g. doors, side covers, top covers; interfaces for misc
46、ellaneous 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 same cabinet with associated mounting uprights; modularity of the frame-based structure supporting shipment in the form of ki
47、ts 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 cabinets of IEC 60917-2-5 without significant technical modifications due to the fact that all follow the same coordination dimen
48、sions. 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 planes and mounting points are defined to be used for attaching miscellaneous equipment or accessories. 6 60917-2-5 IEC:2012 MO
