21 General Advisory Note: In Canada, there are two official languages, English and French. Annex A provides translations in French ofthe English safety markings specified in this standard. Markings required by this standard may have to be provided in other languages to conform with the language requirements of the countrywhere the product is to be used. 21.1 The markings, including signage required for compliance to this standard, shall be legible and permanent such as metal stamped, etched, adhesive labels, etc. An adhesive-backed label shall comply with UL 969, and CSA C22.2 No. 0.15, for the intended exposure conditions and surface adhered to. 21.2 Each current sensor shall be marked with the following: a) Primary voltage, “250 V”, “600 V”, “1000 V”, or “1500 Vdc”. AC rated sensors may instead be marked “Vac”, or “Vac/Vdc”. b) Frequency, Frequencies, or DC; c) Primary Current Rating; d) Secondary Voltage and/or Current Rating; e) Model Designation; and f) Manufacturer’s name or trademark.
21.3 Current sensors evaluated for use in a service entrance location may be marked “Service Entrance”. 21.4 Current sensors marked “Service Entrance” may additionally be marked “Overvoltage Category IV” or “CAT IV”. Non-service entrance types may optionally be marked “Overvoltage Category III” or “CAT III”. 21.5 Current sensors evaluated for controlled environment spacings in accordance with Table 9.3 and Table 9.4, shall be marked “Controlled Environment” or “Pollution Degree 2”. 21.6 Current sensors evaluated for reduced spacings shall be marked, “BASIC INSULATION, use only on insulated conductor, secured from contacting live parts”. See footnotes in Table 9.1 – Table 9.4 and reduced dielectric values in 14.4. 21.7 Current sensors evaluated to the full spacings and dielectric values of Table 9.1, Table 9.2, Table 9.3, Table 9.4 and Table 14.1, may optionally be marked, “REINFORCED INSULATION”. 21.8 The IEC 61010 alternates marking may be used for any of the above items except for Manufacturer’s name or trademark. INSTALLATION INSTRUCTIONS 22 General 22.1 Current sensors installation instructions 22.1.1 Installation instructions must be provided, and shall include the following: a) Intended use of the equipment; b) Electrical ratings; c) Name and address of manufacturer or supplier from whom technical assistance may be obtained; d) Maximum ambient temperature rating if evaluated for greater than 40°C (104°F), and minimum ambient temperature rating if evaluated for less than 5°C (41°F); e) Maximum intended elevation, if evaluated for more than 2000 m (6562 ft); f) Equipment provided with detachable cable assemblies in accordance with 10.7 shall include the cable manufacturer’s name and model designation within the sensor manual for ordering replacement cables in case one is lost or damaged during installation; g) Equipment provided with field wiring terminal blocks in accordance with 10.8 shall have wiring instructions that include: 1) Use only cables with copper conductors and with a gauge of 0.75 mm 2 (18 AWG or lower), or smaller diameter wire if allowed by the NEC, or the Canadian Electrical Code, CSA C22.1. 2) Specification of terminal’s torque rating or range.
22.2 Additional instructions for current sensors 22.2.1 Additional instructions for Current Sensors shall include: a) Current sensors evaluated for reduced spacings in accordance with the footnotes in Table 9.1 – Table 9.4 and reduced dielectric values in accordance with 14.4, shall include the following in the manual, “BASIC INSULATION, use only on insulated conductor, secured from contacting live parts”. b) Instructions for the installation and removal of the current sensor shall also include the following statements 1) Current sensors marked “BASIC INSULATION” shall be installed on insulated conductors only and maintained away from all live parts; and 2) The word “WARNING” and the following or equivalent statement, “To reduce the risk of electric shock, always open or disconnect circuit from power-distribution system (or service) of building before installing or servicing current sensors.” 22.3 Additional instructions for submetering equipment 22.3.1 Additional instructions for submetering equipment shall include: a) The word “WARNING” and the following or equivalent statement, “To reduce the risk of electric shock, always open or disconnect circuit from power-distribution system (or service) of building before installing or servicing submetering equipment.”UL 2808-2020 pdf download.
