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.dition 1.0 2014-11 INTERNATIONAL STANDARD NORME INTERNATIONALE colour inside Junction boxes for photovoltaic modules – Safety requirements and tests Bo？tes de jonction pour modules photovolta？ques – Exigences de sécurité et essais IEC 62790:2014-11(en-fr) THIS PUBLICATION IS COPYRIGHT PROTECTED Copyright ？ 2014 IEC, Geneva, Switzerland All rights reserved.
