33、tems for ElectricVehicle (EV) Supply Circuits: General Requirements. It is the First edition of NMX-J-668/1-ANCE, the Firstedition of CSA C22.2 No. 281.1, and the Second edition of UL 22311. This edition of UL 22311supersedes the previous edition published in 2002.This harmonized standard was prepar

34、ed by the Association of Standardization and Certification (ANCE),CSA Group, and Underwriters Laboratories Inc. (UL). The efforts and support of the TechnicalHarmonization Working Group for Personnel Protection Systems for Electric Vehicle (EV) Supply Circuitsare gratefully acknowledged.This standar

35、d is considered suitable for use for conformity assessment within the stated scope of theStandard.The present Mexican Standard was reviewed and approved by the Comit de Normalizacin de laAsociacin de Normalizacin y Certificacin, A.C., CONANCE.This standard was reviewed by the CSA Subcommittee on Ele

36、ctric Vehicle Personal Protection Systemsfor Supply Circuits, under the jurisdiction of the CSA Technical Committee on Industrial Products and theCSA Strategic Steering Committee on Requirements for Electrical Safety, and has been formallyapproved by the CSA Technical Committee.This standard has bee

37、n approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Where reference is made to a specific number of specimens to be tested, the specified number is to beconsidered a minimum quantity.Note: Although the intended primary application of this standard is stated

38、 in its scope, it isimportant to note that it remains the responsibility of the users of the standard to judge itssuitability for their particular purpose.Level of harmonizationThis standard uses the IEC format but is not based on, nor is considered equivalent to, an IEC standard.This standard is pu

39、blished as an equivalent standard for ANCE, CSA Group, and UL.An equivalent 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 thoserecognized as being in accordanc

40、e with NAFTA Article 905, for example, because of fundamental climatic,geographical, technological, or infrastructural factors, scientific justification, or the level of protection thatthe country considers appropriate. Presentation is word for word except for editorial changes.Reasons for differenc

41、es from IECThis standard provides general requirements for personnel protection systems for electric vehicle supplycircuits for use in accordance with the electrical installation codes of Canada, Mexico, and the UnitedStates. At present there is no IEC standard for these products for use in accordan

42、ce with these codes.Therefore, this standard does not employ any IEC standard for base requirements.SEPTEMBER 7, 2012NMX-J-668/1-ANCE CSA C22.2 NO. 281.112 UL 223114InterpretationsThe interpretation by the standards development organization of an identical or equivalent standard isbased on the liter

If more than one interpretation of the literal text has beenidentified, a revision is to be proposed as soon as possible to each of the standards developmentorganizatio

44、ns to more accurately reflect the intent.ANCE effective dateThe effective date for ANCE will be announced through the Diario Oficial de la Federacin (OfficialGazette) and is indicated on the cover page.CSA Group effective dateThe effective date for CSA Group will be announced through CSA Informs or

47、 from accessible parts, in grounded or isolated circuitsfor 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 chargingsystems and vehicles where use is intended and are rated

48、 accordingly. To assure compatibility, thecharging 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 thevehicle, has one or more of the following:a) Provision for the connection of an equipment grounding conductor during battery charging,unless the vehicle has a system of reinforced or double insulation or all of the circuitry on thevehicle is electrically isolated from the supply circuit,b) Provision for the con
