This International Standard describes safety requirements@ constructional requirements and tests for junction boxes up to 1 500 V dc for use on photovoltaic modules according to class II of IEC 61140:2001. This standard applies also to enclosures mounted on PV-modules containing electronic circuits for converting@ controlling@ monitoring or similar operations. Additional requirements concerning the relevant operations are applied under consideration of the environmental conditions of the PV-modules. This standard does not apply to the electronic circuits of these devices@ for which other IEC-standards apply. NOTE For junction boxes according to classes 0 and III of IEC 61140:2001@ in photovoltaic-systems@ this standard can be used as a guideline.
