IEC 62852-2020 pdf free.Connectors for DC-application in photovoltaic systems – Safety requirements and tests.
IEC 62852 applies to connectors for use in the d.c. circuits of photovoltaic systems according to class Il of IEC 61140:2001 with rated voltages up to 1 500 V d.c. and rated currents up to 125 A per contact.
This standard applies to connectors without breaking capacity but which might be engaged and disengaged under voltage.
This standard also applies to connectors 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 connectors in photovoltaic systems of classes 0 and Ill according to IEC 61140:2001 as well as for protection for Class II equipment intended for use at less than 50 V d.c. 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.
2 Normative references
The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
3 Terms and definitions
For the purposes of this document, the terms and definitions given in IEC 60050-581,IEC 60050-826,IEC 60309-1,1EC 60664-1,IEC 60999-1 and IEC 61140,as well as the following apply.
3.1 connector component which terminates conductors for the purpose of providing connection to and disconnection from a suitable mating component
3.2 multi-way connector connector with more than one contact
Note 1 to entry: Multiple single-way connectors used in a PV-junction box are not to be regarded as a multi-way connector according to this standard.
3.3 connector under voltage CuV connector specially designed to be engaged or disengaged in normal use when live but not under load
Note 1 to entry: In this standard, the term “live” is used if contacts are under an applied voltage, but not necessarily carrying current. The term “load” is used if a current is flowing through the contacts.
3.4 connector without breaking capacity COC  connector which is not allowed to be engaged or disengaged in normal use when live or under load [SOURCE: IEC 60050-581:2008, 581-27-73]
3.5 type of connector
3.5.1 free connector connector for attachment to the free end of a wire or cable.IEC 62852 pdf download.
