IEC publication 61010-2-201 is copyrighted by the IEC. This U

27、L Standard 61010-2-201 Standard for Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory use Part 2-201: Particular Requirements for Control Equipment, is to be used in conjunction with the third edition of UL 61010-1. The requirements for control equipment are conta

28、ined in this Part 2 Standard and UL 61010-1. Requirements of this Part 2 Standard, where stated, amend the requirements of UL 61010-1. Where a particular subclause of UL 61010-1 is not mentioned in UL 61010-2-201, the UL 61010-1 subclause applies. These materials are subject to copyright claims of I

All requests pertaining to the UL 61010-2-201 Standard for Safety Requirements for Electrical Equipment for Measurement, Control, and Laboratory

30、 use Part 2-201: Particular Requirements for Control Equipment Standard should be submitted to UL. Note Although the intended primary application of this Standard is stated in its Scope, it is important to note that it remains the responsibility of the users of the Standard to judge its suitability

31、for their particular purpose.

32、1, Safety requirements for electrical equipment for measurement, control, and laboratory use Part 2-201: Particular requirements for control equipment copyright 2013 are indicated by notations (differences) and are presented in bold text. There are ve types of National Differences as noted below. Th

33、e difference type is noted on the first line of the National Difference in the standard. The standard may not include all types of these National Differences. DR These are National Differences based on the national regulatory requirements. D1 These are National Differences which are based on basic s

34、afety principles and requirements, elimination of which would compromise safety for consumers and users of products. D2 These are national differences from IEC requirements based on existing safety practices. These requirements reect national safety practices, where empirical substantiation (for the

35、 IEC or national requirement) is not available or the text has not been included in the IEC standard. DC These are National Differences based on the component standards and will not be deleted until a particular component standard is harmonized with the IEC component standard. DE These are National

36、Differences based on editorial comments or corrections. Each national difference contains a description of what the national difference entails. Typically one of the following words is used to explain how the text of the national difference is to be applied to the base IEC text: Addition / Add - An

37、addition entails adding a complete new numbered clause, subclause, table, gure, or annex. Addition is not meant to include adding select words to the base IEC text. Modication / Modify - A modication is an altering of the existing base IEC text such as the addition, replacement or deletion of certai

38、n words or the replacement of an entire clause, subclause, table, gure, or annex of the base IEC text. Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause, table, gure, or annex without any replacement text. FEBRUARY 20, 2017 UL 61010-2-201 6AUL COPYRIGHT

40、SAFETY REQUIREMENTS FOR ELECTRICAL EQUIPMENT FOR MEASUREMENT, CONTROL, AND LABORATORY USE Part 2-201: Particular requirements for control equipment FOREWORD 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national electrotechnical

41、 committees (IEC National Committees). The object of IEC is to promote international co-operation on all questions concerning standardization in the electrical and electronic elds. To this end and in addition to other activities, IEC publishes International Standards, Technical Specications, Technic

42、al Reports, Publicly Available Specications (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

43、and nongovernmental organizations liaising 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 agreeme

44、nts of IEC on technical matters express, 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

45、 are accepted by IEC National Committees 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 i

46、nternational uniformity, IEC National 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

47、in the latter. 5) IEC itself does not provide any attestation of conformity. Independent certication 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 certication bodies. 6) All user

48、s should ensure that they have 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 othe

49、r damage of any nature whatsoever, 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 publications 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 b
