This Standard contains specific requirements for lighting systems and is intended to be used together with the requirements for luminaires contained in CSA C22.2 No. 250.0. This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. This Standard was prepared by the Integrated Committee on Lighting Products, under the jurisdiction of the Technical Committee on Consumer and Commercial Products and the Strategic Steering Committee on Requirements for Electrical Safety, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 1.1 This Standard applies to lighting systems equipment that performs a sensing and/or signalling function, to convey data through wired or wireless means to, or from, other components of a field installed lighting system. This equipment is rated at 600 V or less, for commercial, industrial, or residential applications, and intended to be installed in non-hazardous locations in accordance with CSA C22.1, Canadian Electrical Code (CE Code), Part I. 1.2 These requirements cover a) power source equipment, and luminaires that are part of a lighting system; b) luminaires and its remote components connected to Class 2 power and data communication circuits (power over ethernet); and c) extra-low-voltage lighting systems incorporating a power supply, luminaires, and bare or insulated conductors. 1.3 This Standard does not apply to luminaires covered by other applicable CSA Standards, such as a) Decorative lighting products, C22.2 No. 37; b) Retrofit kits for luminaire conversion, C22.2 No. 250.1; c) Emergency lighting equipment, C22.2. No. 141; d) Stage and studio luminaires, C22.2 No. 166; e) Portable and stationary electric signs and displays, C22.2 No. 207; f) Extra-low-voltage landscape lighting systems, C22.2 No. 250.7; g) Swimming-pool luminaires, submersible luminaires, and accessories, C22.2 No. 89; h) Portable luminaires, C22.2 No. 250.4; i) Track lighting, C22.2 No. 250.570; j) Direct plug-in nightlights, C22.2 No. 256; k) Flashlights and lanterns, C22.2 No. 250.5; and l) Horticultural lighting applications and systems, ANSI/CAN/UL 8800. 1.4 The requirements specified in this Standard do not cover light-emitting diode assemblies, components, or controls that are applicable to CSA C22.2 No. 250.13. 1.5 This Standard is intended to be used in conjunction with the applicable clauses of CSA C22.2 No. 250.0 and its subsequent revisions. 1.6 In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard. Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material. Notes to tables and figures are considered part of the table or figure and may be written as requirements. Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 1.7 The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
