24、CSA C22.2 NO. 107.3-14 UL 1778 5PrefaceThis is the harmonized CSA Group and UL Standard for Uninterruptible Power Systems (UPS). It is thethird edition of CSA C22.2 No. 107.3 and the fifth edition of UL 1778. This harmonized standard has beenjointly revised on October 12, 2017.This harmonized Standa
25、rd was prepared by CSA Group and Underwriters Laboratories Inc. (UL). Theefforts and support of the National Electrical Manufacturers Association (NEMA) and Electro-FederationCanada (EFC) are gratefully acknowledged.This standard is considered suitable for use for conformity assessment within the st
26、ated scope of thestandard.This Standard was reviewed by the CSA Subcommittee on Uninterruptible Power Systems, under thejurisdiction of the CSA Technical Committee on Industrial Products and the CSA Strategic SteeringCommittee on Requirements for Electrical Safety, and has been formally approved by
27、the CSA TechnicalCommittee.This Standard has been approved by the American National Standards Institute (ANSI) as an AmericanNational Standard.Application of StandardWhere reference is made to a specific number of samples to be tested, the specified number is to beconsidered a minimum quantity.Note:
28、 Although the intended primary application of this standard is stated in its scope, it is important to note thatit remains the responsibility of the users of the standard to judge its suitability for their particular purpose.The Standard is intended to be used in conjunction with the applicable requ
29、irements of CAN/CSA-C22.2No. 60950-1-07 and UL 60950-1, March 2007, second edition, which is referred to in this Standard as theReference Document (RD). Compliance will be determined by the requirements located inCAN/CSA-C22.2 No. 60950-1-07 and UL 60950-1, March 2007, second edition, with deviation
30、s presentedin the third edition of CSA C22.2 No. 107.3 and the fifth edition of UL 1778.Level of HarmonizationThis Standard is published as an equivalent standard for CSA Group and UL. An equivalent standard isa standard that is substantially the same in technical content, except as follows: Technic
31、al nationaldifferences are allowed for codes and governmental regulations as well as those recognized as being inaccordance with NAFTA Article 905, for example, because of fundamental climatic, geographical,technological, or infrastructural factors, scientific justification, or the level of protecti
32、on that the countryconsiders appropriate. Presentation is word for word except for editorial changes.InterpretationsThe interpretation by the standards development organization of an identical or equivalent standard isbased on the literal text to determine compliance with the standard in accordance
33、with the proceduralrules of the standards development organization. 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 developmentOCTOBER 12, 2017CSA C22.2 NO. 107.3-14 UL 17786organizations to more accura
34、tely reflect the intent.OCTOBER 12, 2017 CSA C22.2 NO. 107.3-14 UL 1778 7Uninterruptible Power Systems1 General1.1 ScopeReplace this clause of the RD with the following:1.1.1 Equipment covered by this StandardThis Standard applies to UNINTERRUPTIBLE POWER SYSTEMS (UPS). The primary function of the U
35、PS for thisStandard is to ensure continuity of an alternating power source. The UNINTERRUPTIBLE POWER SYSTEM may alsoserve to improve the quality of the power source by keeping it within specified characteristics. ThisStandard is applicable to movable, stationary, fixed, and built-in UPS for distrib
36、ution systems up to 600 Va.c. This equipment is designed to be installed in accordance with the Canadian Electrical Code, Part I,CSA C22.1, or the National Electrical Code, ANSI/NFPA 70, and, unless otherwise identified, theStandard for the Protection of Electronic Computer Data-Processing Equipment
37、, ANSI/NFPA 75.This Standard specifies requirements intended to ensure safety for the OPERATOR and, where specificallystated, for SERVICE PERSONNEL.This Standard is intended to reduce the risk of fire, electric shock, or injury to persons from installedequipment, both as a single unit or as a system
38、 of interconnected units, subject to installing, operating,and maintaining the equipment in the manner prescribed by the manufacturer.1.1.2 Additional requirementsIn addition to the requirements in this Standard, a UPS is to comply with the UPS-relevant requirementsof CAN/CSA-C22.2 No. 60950-1/UL 60
39、950-1, March 2007, second edition, Information TechnologyEquipment Safety Part 1: General requirements (RD), as applicable for the country where the productwill be used. Wherever there is a conflict between the requirements of this Standard and the RD, therequirements of this Standard will prevail.E
40、ngine-driven d.c. power generators intended to provide backup power for the battery supply circuit of UPSunits are investigated for compliance with the requirements of UL 2200, and CSA C22.2 No. 100.UPS that employ hospital grade components identified by the markings Hospital Only, Hospital Grade”,o
41、r a green dot on the BODY of the component, or otherwise implying suitability for medical use, areevaluated to the requirements of this Standard and CAN/CSA-C22.2 No. 60601-1/UL 60601-1.Requirements additional to those specified in this Standard may be necessary for equipment intended foruse where i
42、ngress of water is possible; for guidance on such requirements and on relevant testing, seeAnnex LLL and Annex T/RD.OCTOBER 12, 2017CSA C22.2 NO. 107.3-14 UL 177881.1.3 ExclusionsThese requirements do not cover UPS units for use as legally required standby systems, described inArticle 701 of the Nat
43、ional Electrical Code, ANSI/NFPA 70, and emergency power supply described inSection 46 of the Canadian Electrical Code, Part I, CSA C22.1. See Annex LLL.Where considered appropriate, revision of requirements will be proposed and adopted in conformancewith the methods employed for development, revisi
44、on, and implementation of this Standard.NOTE 1: For equipment subject to transient overvoltages exceeding those for Category II according to IEC 60664,additional protection might be necessary. Such additional protection may be located in the AC MAINS SUPPLY tothe equipment or in the equipment as an
45、integral design feature.NOTE 2 Where the additional protection is an integral part of the equipment insulation requirements, CREEPAGEDISTANCES and CLEARANCE distances from the mains through to the load side of the additional protection maybe judged as Category III or IV as required. All insulation r
46、equirements, CREEPAGE DISTANCES, andCLEARANCE distances on the load side of the additional protection may be judged as Category I or II as required.1.1.4 Additional applicationsThis Standard does not cover all types of UPS, but it may be taken as a guide for such equipment.Requirements additional to
47、 those specified in this Standard are in some cases necessary for specificapplications, e.g.,a) equipment intended for operation while exposed to conditions such as extremes oftemperature; excessive dust, moisture, or vibration; flammable gases; or corrosive or explosiveatmospheres;b) UPS equipment
48、based on rotary machinery;c) UPS equipment meeting emergency lighting and power requirements as specified in UL 924;and central power system described in CSA C22.2 No 141-10.Additional subclause:JUNE 13, 2014 CSA C22.2 NO. 107.3-14 UL 1778 91.1.101 Normative referencesAny undated reference to a code
