26、d is used to evaluate both motors intended to be eld installed as well as those intended to be factory installed. Motors intended to be factory installed need not comply with the requirements in Section 12, Ventilation Openings; Section 13, Accessibility of Uninsulated Live Parts, Film-Coated Wire,

27、and Moving Parts; 16.9 16.16, 16.28, 18.1 18.5, 33.1 33.3, 33.5 33.7, and 34.1. 1.3 For the purposes of this Standard, the term “machine” is representative of and equivalent to the terms rotating electrical machine and rotating machine, and is understood to mean all manner of electric motors and gen

28、erators covered by the scope of this Standard. The term “machine” is understood to apply to both AC and DC machines. 1.4 These requirements do not cover machines intended for use in hazardous locations as dened in the National Electrical Code, NFPA 70. The National Electrical Code and NEC are regist

29、ered trademarks of the National Fire Protection Association, Inc., Quincy, MA 02169 1.5 These requirements do not cover sealed (hermetic type) motor-compressor parts, which are evaluated under the Standard for Hermetic Refrigerant Motor-Compressors, UL 984. 1.6 If the risk of re does not exist at a

30、machine, part, or circuit, then the requirements of this Standard and associated parts of this Standard, intended to address the risk of re shall not apply to that machine, part, or circuit. 1.7 If the risk of electric shock does not exist at a machine, part, or circuit, then the requirements of thi

31、s Standard and associated parts of this Standard, intended to address the risk of electric shock shall not apply to that machine, part, or circuit. 1.8 The requirements of this Standard and associated parts of this Standard, intended to address the risk of re do not apply to a motor provided with a

32、metal enclosure in which there are no openings in the enclosure through which molten metal, burning insulation, aming particles, or other ignited material could fall onto ammable material, or through which a ame could be projected.
