The requirements of this Standard apply to the following electrical equipment for elevators, escalators, moving walks, dumbwaiters, material lifts, and levating devices for persons with physical disabilities (platform lifts and stairway chairlifts): (a) motor controllers; (b) motion controllers; (c) operation controllers; (d) operating devices; and (e) all other electrical equipment not listed/certified and labelled/marked according to another product safety standard or code. The equipment specified in this Standard is intended for installation in accordance with the Canadian Electrical Code, Part I (CSA C22.1) and the National Electrical Code (NFPA 70), whichever is applicable. Note: Controllers, i.e., motion, motor, and operation controllers, are defined in CSA B44 and ASME A17.1. The electrical equipment covered by this Standard is intended (a) to be connected to supply circuits at a nominal system voltage of 600 V or less; (b) for internal voltages that are not more than 1500 V; and (c) for use in non-hazardous locations in accordance with the rules of the applicable electrical codes. The object of this Standard is to reduce the risk of injury to persons and damage to property from fire and electrical shock by presenting requirements for the proper design, the good construction, and the high quality of work of the equipment listed in Clause 1.1. This Standard does not apply to devices that are rated for connection to extra-low-voltage Class 2 supply circuits as defined in the applicable electrical code. Note: Extra-low-voltage circuits are circuits that have a voltage of not more than 30 V rms or 42.4 V peak.
