This document specifies safety requirements for the following track systems with two or more poles for the connection of luminaires to the electrical supply consisting of, either
a) a system with provision for protective earthing and with a rated voltage not exceeding 440 V between poles and where the rated current does not exceed 16 A per conductor, for use with class I and class II luminaires, or
b) a system without provision for protective earthing where protection against electric shock is based on a SELV supply and where the rated current does not exceed 25 A per conductor, for use with class III luminaires, or
c) a combination of a) and b) for connecting both class I and class II luminaires and class III luminaires simultaneously but in different sector openings.”
The track systems can also provide for the mechanical support of the luminaires.
This document applies to track systems designed for ordinary interior use for mounting on, or flush with, or suspended from walls and ceilings. These track systems are not intended for locations where special conditions prevail as in ships, vehicles and the like and in hazardous locations, for example, where explosions are liable to occur.
This document does not cover operational or performance compatibility between different track
systems. Protection against unsafe compatibility between Class I and Class III circuits is covered by this document. In addition to supply circuits, the track system can be provided with auxiliary circuits such as
those for the purpose of a control or audio signal.
NOTE At present, on the market, the following types of control systems are available:
− FELV control signal, basic insulated from mains supply (e.g. Digital Addressable Lighting Interface and 1–10 V DC controls);
− SELV or PELV control signal (e.g. DMX);
− control signal, not insulated from mains supply (e.g. push button control, phase cut, step dim).
Track systems can also be provided with conductors specifically identified for powering emergency lighting luminaires.
