This part of IEC 60598 specifies requirements for extra- -voltage lighting systems for ELV light sources, intended for ordinary interior use on supply voltages not exceeding 1 000 V. The luminaires, being connected In parallel, are suppl.ed via freely suspended continuous supporting conductors or profiles, the current in the ELV part of the system not exceeding 25 A,

23.3 Terms and definitions
For the purposes of this document, the terms and definitions given in Part 1 and the following apply (see Figure 1).
ISO and IEC maintain terminological databases for use in standardization at the following addresses:
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 23.7.11.
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
SE LV.
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 61558-2-6 or IEC 61558-2-16, 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 61347-2-2 or IEC 61347-2-13, 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 900 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.
