37、D INSTALLATIONS 1 Scope This standard applies to two up to five wire installation couplers including earth, if provided, with a rated voltage up to and including 500 V a.c. and a rated connecting capacity up to and including 10 mm for permanent connection in indoor electrical installations. Installa
38、tion couplers with additional contacts for voltages other than mains voltages are outside the scope of this standard. NOTE 1Installation couplers according to this standard are used e.g. in prefabricated buildings, installation cavities, such as suspended floors and ceilings, or cable tray systems,
39、cable ladder systems, cable ducting systems and cable trunking systems or in commercial show rooms, in partition walls and in any similar application or in furniture complying with IEC 60364-7-713. NOTE 2This standard may be used as a guide for installation couplers with additional contacts for volt
40、ages other than mains voltages. NOTE 3In the UK, where installation couplers have more than 5 wires, they shall meet the requirements of IEC 61535 as though they were included in the scope and shall be tested in such a way that all of the mains voltage pins are subjected to the same level of testing
41、. NOTE 4In the USA, these installation couplers are not permitted to be used where they will not be visible after installation. An installation coupler consists of an installation female connector and an installation male connector for permanent connection not intended to be engaged or disengaged un
42、der load nor to be engaged or disengaged other than during first installation or during reconfiguration or maintenance of the wiring system in which installation couplers have been installed. This means that installation couplers are only intended for infrequent use. Installation couplers are not su
43、itable for use in place of socket-outlet systems. Installation couplers are not suitable for use in place of devices for connecting luminaires (DCLs) according to IEC 61995 or luminaire supporting couplers (LSCs). NOTE 5For lower limits of in-service temperatures the necessary information is given i
44、n the manufacturers installation instructions. In locations where special conditions prevail, as in ships, vehicles and the like and in hazardous locations, for example where explosions are liable to occur, special constructions may be required. NOTE 6Particular requirements for installation coupler
45、s e.g. for. use at higher ambient temperatures, with higher mechanical durability (e.g. metal housings), with higher fire resistance and for use in control circuits (e.g. SELV), are under consideration. NOTE 7National rules may have requirements concerning the accessibility of installation couplers.
46、 NOTE 8Installation couplers are intended to be installed by instructed or skilled persons. NOTE 9National rules may specify who is allowed to carry out the connection and disconnection of installation couplers. 2 Normative references The following referenced documents are indispensable for the appl
