19、eration during their expected lifetime. Specific topics are provided to assess the prevention of electrical shock, fire hazards, and personal injury due to mechanical and environmental stresses. This part of EN 61730 pertains to the particular requirements of construction. EN 61730-2 outlines the re

20、quirements of testing.This standard attempts to define the basic requirements for various application classes of PV modules, but it cannot be considered to encompass all national or regional building codes. The specific requirements for marine and vehicle applications are not covered. This standard

21、is not applicable to modules with integrated AC inverters (AC modules).This standard is designed so that its test sequence can coordinate with those of IEC 61215 or IEC 61646, so that a single set of samples may be used to perform both the safety and performance evaluation of a photovoltaic module d

22、esign.The object of this document is to provide basic guidance in certifying the fundamental construction of photovoltaic modules presented for safety approval by testing under EN61730-2. These requirements are intended to minimise the misapplication and misuse of modules or the breakdown of interna

23、l components which would result in fire, electric shock and personal injury. The standard defines the basic safety construction requirements and additional tests that are a function of the module end-use applications.Component requirements are intended to provide evidence of performance of that comp

24、onent appropriate to its application in the module construction and environment.NOTE The additional construction requirements outlined in relevant ISO standards, or the national or local codes which govern the installation and use of these modules in their intended locations, should be considered in

25、 addition to the requirements contained within this document.2 Normative referencesSee Annex ZA.3 Application classes3.1 GeneralPhotovoltaic modules may be installed in many different applications. Therefore, it is important to evaluate the potential hazards associated with those applications and to

26、 evaluate the construction of the module accordingly.Relevant safety requirements and necessary tests shall be performed to verify the conformance to the requirements of that application class. This clause defines those application classes and construction qualities required for each class.Applicati

27、on classes for PV-modules are defined as follows:3.2 Class A: General access, hazardous voltage, hazardous power applicationsModules rated for use in this application class may be used in systems operating at greater than 120 V DC. Modules qualified for safety through this part of EN 61730 and EN 61

28、730-2 within this application class are considered to meet the requirements for safety class II.3.3 Class B: Restricted access, hazardous voltage, hazardous power applicationsModules rated for use in this application class are restricted to systems protected from public access by fences, location, e

29、tc. Modules evaluated within this application class provide protection by basic insulation, are considered to meet the requirements for safety class 0.3.4 Class C: Limited voltageModules rated for use in this application class are restricted to systems operating at less than120 V DC. Modules qualifi

30、ed for safety through this part of EN 61730 and EN 61730-2 within this application class are considered to meet the requirements for safety class III.NOTE Safety classes are defined within EN 61140.4 Construction requirements4.1 General requirements4.1.1All modules shall be able to operate under env

31、ironmental condition type AB8 according to IEC 60364-5-51.4.1.2A module shall be completely assembled when shipped from the factory, or shall be provided in subassemblies, provided assembly of the product does not involve any action that is likely to affect compliance with the requirements of the EN

32、 61730 series.4.1.3An assembly part, such as a terminal compartment cover, need not be affixed to the module at the factory. Incorporation of a module into the final assembly shall not require any alteration of the module from its originally evaluated form, unless specific details describing necessa

33、ry modification(s) are provided in the installation instructions.4.1.4If a module must bear a definite relationship to another module for the intended installation and operation (for example, to allow connectors to mate), it shall be constructed to permit incorporation into the final assembly without the need for alteration.4.1.5The construction of a module shall be such that ground continuity is not interrupted by installation.4.1.6Parts shall be pr
