AS NZS 62852 pdf download.Connectors for DC-application in photovoltaic systems — Safety requirements and tests (IEC 62852:2014, MOD)
1 Scope
This International Standard applies to connectors for use in the d.c. circuits of photovoltaic systems according to class II of IEC 61 1 40:2001 with rated voltages up to 1 500 V d.c. and rated currents up to 1 25 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 III according to IEC 61 1 40:2001 as well as for protection for Class II equipment intended for use at less than 50 V d.c.
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 , IEC 60664-1 , IEC 60999-1 and IEC 61 1 40, 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 [SOURCE: IEC 60050-581 :2008, 581 -06-01 ] 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 [SOURCE: IEC 60050-581 :2008, 581 -06-1 2] 3.5.2 built-in connector a pre-manufactured connector that is subsequently integrated into an enclosure 3.5.3 integrated connector a connector assembly that is manufactured as an integral component during enclosure fabrication 3.6 non-rewirable connector connector so constructed that the cable cannot be separated from the connector without making it permanently useless [SOURCE: IEC 60309-1 :1 999, 2.5, modified] 3.7 connector for Class II equipment connector in which the protection against indirect contact is realised by double or reinforced insulation Note 1 to entry: Class II according to IEC 61 1 40. 3.8 intended use application conditions of connectors which are included within the permissible rated values and environmental conditions and characteristics assigned by the manufacturer 3.9 interlock device, either electrical or mechanical, which prevents the contacts of a connector from becoming live before it is in proper engagement with its counterpart, and which either prevents the connector from being withdrawn while its contacts are live or makes the contacts dead before separation [SOURCE: IEC 60309-1 :1 999, 2.9, modified] 3.1 0 cycle of mechanical operation one insertion and one withdrawal of the connector with his counterpart 3.1 1 clamping unit part(s) of the terminal necessary for the mechanical clamping and the electrical connection of the conductor(s), including the parts which are necessary to ensure the correct contact pressure [SOURCE: IEC 60999-1 :1 999, 3.1 ]3.1 2 upper limiting temperature maximum temperature of a connector as defined by the manufacturer, in which the connector is intended to operate Note 1 to entry: The abbreviation ULT is often used. 3.1 3 ambient temperature maximum temperature of the ambient assigned from the manufacturer, in which the connector is able to operate permanently without the upper limiting temperature being exceeded 3.1 4 lower limiting temperature minimum temperature of a connector as defined by the manufacturer in which a connector is intended to operate Note 1 to entry: The abbreviation LLT is often used. 3.1 5 clearance the shortest distance in air between two conductive parts [SOURCE: IEC 60664-1 :2007, 1 .3.2] 3.1 6 creepage distance shortest distance along the surface of the insulating material between two conductive parts [SOURCE: IEC 60664-1 :2007, 1 .3.3] 3.1 7 overvoltage category numeral defining a transient overvoltage condition [SOURCE: IEC 60664-1 :2007, 1 .3.1 0]
