AS NZS 60598.2.23 pdf download Luminaires Part 2.23: Particular requirements — Extra-low-voltage lighting systems for ELV light sources (IEC 60598-2-23:2020 (ED.2.0) MOD)
The installation instructions shall clearly and unambiguously state:
a) how the extra-low-voltage lighting system is to be mounted, and in particular, the maximum permitted distance between the main supports and the spacing of auxiliary supports;
b) whether special requirements, for example due to characteristics of the transformer/convertor/controlgear, shall be observed for components of an existing mains supply to which the extra- -voltage lighting system is to be connected, for example socket-outlets, switches, dimmers;
c) that the supporting conductors of different extra- -voltage lighting systems shall be mounted so as not to be able to come into contact with each other, where applicable;
d) that the extra- -voltage lighting system shall not be extended beyond the number of luminaires belonging to the complete set, and that only parts assigned by the manufacturer shall be used;
e) that no additional attachments, for example for decorative purposes, shall be used; f) that the following warning statement be provided: WARNING o avoid the risk of overheating and fire, do not bridge the conductors; g) the positions or spacings for the connections of luminaires (if applicable).
23.7 Construction The provisions of Section 4 of Part 1 apply, together with the requirements of 23.7.1 to 23.7.1 1 .
23.7.1 The whole set of the extra- -voltage lighting system, as delivered by the manufacturer, shall be complete, including the transformer or convertor/controlgear. The secondary side of the extra- -voltage lighting system shall comply with the requirements of SELV. Compliance is checked by mounting as in normal use, inspection and by the applicable measurements and tests required by this document.
23.7.2 Transformers, power supply units or switch mode power supply units provided with safety extra- -voltage lighting systems shall be of the safety isolating type, complying with the requirements of IEC 61 558-2-6 or IEC 61 558-2-1 6, and having a rated output voltage not exceeding 25 V RMS or 60 V ripple free DC.
23.7.3 Convertors/controlgear provided with safety extra-low-voltage lighting systems shall be of the safety isolating type, complying with IEC 61 347-2-2 or IEC 61 347-2-1 3, and having a rated output voltage not exceeding 25 V RMS or 60 V ripple free DC.
23.7.4 Supporting conductors shall be continuous and shall be capable of supporting five times the mass of the luminaires (including their lamps) intended to be connected to them. Compliance is checked by applying a load at 90° to the conductors to the mid-point of a maximum span equal to five times the weight of the luminaires and lamps supplied with the system, with a minimum load of 10 kg, for a period of 1 h, applied simultaneously to both conductors. After the test, the load is removed and the deflection from the normal position shall not exceed 10 % of the distance between the supporting conductors measured before applying the load. If pin contacts or edge contacts are used in the system, then the supporting conductors shall have been subjected to 25 piercings at different places before the test.
23.7.5 Luminaire connectors shall be capable of supporting five times the mass of the luminaire (including its light source) without permanent deformation.
Compliance is checked by the test of 4.14.1 of Part 1 with a minimum load of 1,5 kg. The test shall be carried out after the test of 23.10.1, if applicable.
23.7.6 Short-circuit protection: Adequate means shall be provided to prevent impairing of safety due to unintended short-circuiting of uninsulated accessible SELV conductors of opposite
polarity.
Compliance is checked by the test of 4.26.2 of Part 1.
23.7.7 Lampholders shall comply with the relevant IEC specifications.
Compliance is checked by inspection.
23.7.8 Instructions for use provided by the lamp manufacturers shall be observed.
Compliance is checked by inspection.
23.7.9 Electrical connections to supporting conductors shall not be subject to mechanical tension.
Compliance is checked by inspection.
23.7.10 Provisions shall be made for the extra-low-voltage lighting system to be insulated from the supporting structure.
23.7.11 The rated current of the system shall be limited to 25 A.
Compliance is checked by inspection and by rated data.
23.8 Creepage distances and clearances
The provisions of Section 1 1 of Part 1 apply.
23.9 Provisions for earthing
The provisions of Section 7 of Part 1 apply.
23.10 Terminals and electrical connections
The provisions of Sections 1 4 and 1 5 of Part 1 , including the electrical tests, apply, together with the requirements of 23.1 0.1 to 23.1 0.3.
