It is the First edition of NM
27、X-J-668/1-ANCE, the First edition of CSA C22.2 No. 281.1, and the Second edition of UL 22311. This edition of UL 22311 supersedes the previous edition published in 2002. This harmonized standard was prepared by the Association of Standardization and Certifi cation (ANCE), CSA Group, and Underwriters
28、 Laboratories Inc. (UL). The efforts and support of the Technical Harmonization Working Group for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits are gratefully acknowledged. This standard is considered suitable for use for conformity assessment within the stated scope of the
29、Standard. The present Mexican Standard was reviewed and approved by the Comit de Normalizacin de la Asociacin de Normalizacin y Certifi cacin, A.C., CONANCE. This standard was reviewed by the CSA Subcommittee on Electric Vehicle Personal Protection Systems for Supply Circuits, under the jurisdiction
30、 of the CSA Technical Committee on Industrial Products and the CSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the CSA Technical Committee. This standard has been approved by the American National Standards Institute (ANSI) as an American Nat
31、ional Standard. Where reference is made to a specifi c number of specimens to be tested, the specifi ed number is to be considered a minimum quantity. Note: Although the intended primary application of this standard is stated in its scope, it is important to note that it remains the responsibility o
32、f the users of the standard to judge its suitability for their particular purpose. Level of harmonization This standard uses the IEC format but is not based on, nor is considered equivalent to, an IEC standard. This standard is published as an equivalent standard for ANCE, CSA Group, and UL. An equi
33、valent standard is a standard that is substantially the same in technical content, except as follows: Technical national differences are allowed for codes and governmental regulations as well as those recognized as being in accordance with NAFTA Article 905, for example, because of fundamental clima
34、tic, geographical, technological, or infrastructural factors, scientifi c justifi cation, or the level of protection that the country considers appropriate. Presentation is word for word except for editorial changes. Reasons for differences from IEC This standard provides general requirements for pe
35、rsonnel protection systems for electric vehicle supply circuits for use in accordance with the electrical installation codes of Canada, Mexico, and the United States. At present there is no IEC standard for these products for use in accordance with these codes. Therefore, this standard does not empl
36、oy any IEC standard for base requirements. SEPTEMBER 7, 2012NMX-J-668/1-ANCE CSA C22.2 NO. 281.112 UL 2231-14 Interpretations The interpretation by the standards development organization of an identical or equivalent standard is based on the literal text to determine compliance with the standard in
37、accordance with the procedural rules of the standards development organization. If more than one interpretation of the literal text has been identifi ed, a revision is to be proposed as soon as possible to each of the standards development organizations to more accurately refl ect the intent. ANCE e
38、ffective date The effective date for ANCE will be announced through the Diario Ofi cial de la Federacin (Official Gazette) and is indicated on the cover page. CSA Group effective date The effective date for CSA Group will be announced throughCSA Informs or a CSA Group certifi cation notice. UL effec
39、tive date As of September 7, 2012, all products Listed or Recognized by UL must comply with the requirements in this Standard. A UL effective date is one established by Underwriters Laboratories Inc. and is not part of the ANSI approved standard. SEPTEMBER 7, 2012NMX-J-668/1-ANCE CSA C22.2 NO. 281.1
40、12 UL 2231-15 Personnel Protection Systems for Electric Vehicle (EV) Supply Circuits: General Requirements 1 Scope 1.1 These requirements cover devices and systems intended for use in accordance with Annex A, Ref. No. 1, to reduce the risk of electric shock to the user from accessible parts, in grou
41、nded or isolated circuits for charging electric vehicles. These circuits are external to or on board the vehicle. 1.2 The devices and systems covered by these requirements are compatible with the designs of charging systems and vehicles where use is intended and are rated accordingly. To assure comp
42、atibility, the charging system, the vehicle, or both, are in accordance with the features contained in 1.3 1.5. 1.3 The type of vehicle covered by these requirements, including all accessible conductive parts on the vehicle, has one or more of the following: a) Provision for the connection of an equ
43、ipment grounding conductor during battery charging, unless the vehicle has a system of reinforced or double insulation or all of the circuitry on the vehicle is electrically isolated from the supply circuit, b)Provision for the connection of ground-monitoring conductors, where required, c) Reinforce
44、d insulation, or is double-insulated from the supply circuit, or d) No direct connection between current-carrying conductors and the vehicle chassis. 1.4 These requirements cover devices and systems where the grounding path impedance of the charging system to the vehicle is less than or equal to the
45、 impedance of the ungrounded conductor or conductors. 1.5 These requirements cover devices and systems where a continuous current less than 70 mA RMS is available from any accessible part of the charging system. 1.6 Devices covered by these requirements are intended to interrupt the electric circuit
46、 to the load when: a)A fault current to ground exceeds some predetermined value that is less than that required to operate the overcurrent protective device of the supply circuit, b)The grounding path becomes open-circuited or becomes an excessively high impedance, or c)A path to ground is detected
47、on an isolated (ungrounded) system. 1.7 These devices and systems are intended to be applied on electrical systems or include derived systems that are: a)Either end-grounded or centrally grounded when the operating voltage is 150 Vrms or less, b)Centrally grounded when the operating voltage is great
48、er than 150 Vrms, or c)Isolated (ungrounded). SEPTEMBER 7, 2012NMX-J-668/1-ANCE CSA C22.2 NO. 281.112 UL 2231-16 1.8 Charging circuit-interrupting devices covered by these requirements are investigated for their ability to provide protection based on: a)The type of current (60 Hz AC, DC, a combinati
49、on of AC and DC, or AC at frequencies greater than 60 Hz) present in the circuit to be protected, and b)Voltage. 1.9 In Mexico and the US, these requirements do not cover ground-fault circuit-interrupters (GFCIs) intended for use as personnel protection in accordance with the national electrical codes on grounded 120 Vrms or 127 Vrms to ground, 60 Hz circuits. Such devices are covered under Annex A, Ref. No. 2. In Canada, these requirements do not cover ground-fault circuit-interrupters (GFCIs) in accordance with the national electrical code on grounded 120 Vrms or 12
