1.1 Inclusions
The requirements of this Standard apply to the following electrical equipment for elevators, escalators, moving walks, dumbwaiters, material lifts, manlifts, wind turbine elevators, ,and platform lifts and stair lifts for barrier-free access (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 (ANSI/NFPA 70), whichever is applicable.
Note: Controllers (i.e., motion, motor, and operation controllers) are defined in CSA B44 and ASME A17.1.
1.2 Electrical equipment covered by this Standard
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;
c) for use in non-hazardous locations in accordance with the rules of the applicable electrical codes; and
d) for use in an ambient temperature no greater than 40 °C.
Note: This Standard does not include requirements for equipment intended for use in an ambient temperature above 40 °C. Additional investigation of the equipment will be required when equipment is to be used in ambient temperature above 40 °C.
1.3 Objective of this Standard
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.
1.4 Terminology
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.
1.5 Units
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.
