Foreword This Standards Publication is a NEMA Adoptive Standar

14、d based on Part 7 of IEC 61131, Programmable Controllers. This Standards Publication was prepared by a technical committee of the NEMA Automation Products and Systems Section. It was approved in accordance with the bylaws of NEMA and supersedes NEMA Standards Publication ICS 3-1988, Part 3-304. This

15、 Standards Publication provides practical information concerning ratings, construction, test, performance, and manufacture of industrial control equipment. These standards are used by the electrical industry to provide guidelines for the manufacture and proper application of reliable products and eq

16、uipment and to promote the benefits of repetitive manufacturing and widespread product availability. NEMA Standards represent the result of many years of research, investigation, and experience by the members of NEMA, its predecessors, its Sections and Committees. They have been developed through co

17、ntinuing consultation among manufacturers, users, and national engineering societies and have resulted in improved serviceability of electrical products with economies to manufacturers and users. One of the primary purposes of this Standards Publication is to encourage the production of reliable con

18、trol equipment which, in itself, functions in accordance with these accepted standards. Some portions of these standards, such as electrical spacings and interrupting ratings, have a direct bearing on safety; almost all of the items in this publication, when applied properly, contribute to safety in

19、 one way or another. Properly constructed industrial control equipment is, however, only one factor in minimizing the hazards which may be associated with the use of electricity. The reduction of hazard involves the joint efforts of the various equipment manufacturers, the system designer, the insta

20、ller, and the user. Information is provided herein to assist users and others in the proper selection of control equipment. The industrial control manufacturer has limited or no control over the following factors which are vital to safe installation: null environmental conditions null system design

21、null equipment selection and application null installation null operating practices null maintenance This publication is not intended to instruct the user of control equipment with regard to these factors except insofar as suitable equipment to meet needs can be recognized in this publication and so

22、me application guidance is given. This Standards Publication is necessarily confined to defining the construction requirements for industrial control equipment and to providing recommendations for proper selection for use under normal or certain specific conditions. Since any piece of industrial con

23、trol equipment can be installed, operated, and maintained in such a manner that hazardous conditions may result, conformance with this publication does not by itself assure a safe installation. When, however, equipment conforming with these standards is properly selected and is installed in accordan

24、ce with the National Electrical Code and properly maintained, the hazards to persons and property will be reduced. NEMA IA 2.7-2005 Page iii Copyright 2005 by the National Electrical Manufacturers Association. To continue to serve the best interests of users, NEMA is actively cooperating with other

25、standardization organizations in the development of simple and more universal metrology practices. In this Standards Publication, the U.S. customary units are gradually being supplemented by those of the modernized metric system known as the International Systems of Units (SI). This transition invol

26、ves no changes in standard dimensions, tolerances, or performance specifications. NEMA Standards Publications are subject to periodic review. They are revised frequently to reflect user input and to meet changing conditions and technical progress. Users should secure the latest editions. Inquiries,

27、comments, and proposed or recommended revisions should be submitted to the concerned NEMA product subdivision by contacting the: Vice President, Technical Services National Electrical Manufacturers Association 1300 North 17th Street Rosslyn, Virginia 22209 NEMA IA 2.7-2005 Page iv Copyright 2005 by
