This International Standard applies to PV couplers for use in the d.c. circuits of photovoltaic systems according to IEC 60364-7-712 and PV arrays according to IEC 62548-1, categorized as class II of IEC 61140 with rated voltages up to 1 500 V d.c. and rated currents up to 125 A per contact.
This standard applies to PV couplers consisting of connectors from same product family of same manufacturer without breaking capacity, but which are able to be engaged and disengaged under voltage (i.e. when live, Connector under voltage (CuV)).
Note 1 to entry: The meaning of “manufacturer” is described in 3.3.
This standard also applies to connectors for PV couplers which are intended to be built-in or integrated in enclosures of devices for photovoltaic systems. This standard may be used as a guide for PV couplers in photovoltaic systems of classes 0 and III according to IEC 61140. This document does not apply to connectors for data collection, tracker controls or similar, but it may be used as a guide for those connectors.
This standard does not cover any requirement which may be applied for tests of combinations of plugs and sockets from different manufacturers.
Note 2 to entry: IEC 63678, Standardized plug and socket design for DC photovoltaic (PV) systems for intermatability of connectors from different manufacturers is in development.
