28、600 volts for use in accordance with the National Electrical Code, ANSI/NFPA 70. 1.2 These requirements cover open-type appliances intended to be factory or eld installed in vending machines and other appliances. 1.3 These requirements cover open-type controls for use with coin, credit card, debit c

29、ard, currency, and token-operated devices intended to be factory installed within vending machines and other appliances. 1.4 These requirements do not cover the effectiveness of antitheft protection features. 1.5 Battery operated coin and currency changers and actuators are covered by these requirem

30、ents. 2 Glossary 2.1 For the purpose of this standard, the following denitions apply. 2.2 ADJUSTABLE SPEED DRIVE A combination of power converter, inverter, motor, and motor-mounted auxiliary devices such as encoders, tachometers, thermal switches and detectors, air blowers, heaters, and vibration s

31、ensors. 2.3 ADJUSTABLE SPEED DRIVE SYSTEM An interconnected combination of equipment that provides a means of adjusting the speed of a mechanical load coupled to a motor. A drive system typically consists of an adjustable speed drive and auxiliary electrical apparatus. 2.4 APPLIANCE Denotes all coin

32、, credit card, debit card, currency, and token changers and actuators included in the scope of this standard. A requirement that applies only to specic equipment is identied by a specic reference in that requirement to the equipment involved. 2.5 BARRIER A partition for isolating high-voltage electr

33、ical components, separating ignition sources from ammable materials, isolating moving parts and protection of wiring. 2.6 CABINET The part of the equipment that provides physical protection to insulated wiring, enclosures, moving parts, motors, enclosed electrical parts, tubing or other parts that m

34、ay cause injury to persons. 2.7 CIRCUITS, ELECTRICAL a) High-Voltage (Class 1) A circuit involving a potential of not more than 600 volts and having circuit characteristics in excess of those of a low-voltage power-limited circuit. b) Low-Voltage A circuit involving a potential of not more than 30 v

35、olts AC rms, 42.4 volts DC or AC peak. c) Power-Limited A circuit whose output is limited as specied in Power-Limited Circuits, Section 62.

36、SSION FROM UL d) Class2Acircuit in which the voltage and power limitations are in accordance with the Class 2 requirements of Table 62.1 for AC circuits and Table 62.2 for DC circuits. e) Class3Acircuit in which the voltage and power limitations are in accordance with the Class 3 requirements of Tab

37、le 62.1 for AC circuits and Table 62.2 for DC circuits. 2.8 COMPONENT A device or fabricated part of the appliance covered by the scope of a safety standard dedicated to that purpose. If incorporated in an appliance, a product that is otherwise typically eld installed (e.g. luminaire) is considered

38、to be a component. Unless otherwise specied, materials that compose a device or fabricated part, such as aluminum or copper, are not considered components. Generally, components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use on

39、ly under specic, limited conditions, such as certain temperatures not exceeding specied limits. 2.9 CONTROL, OPERATING A device or assembly of devices, the operation of which starts or regulates the end product during normal operation. For example, a thermostat, the failure of which a thermal cutout

40、/limiter or another layer of protection would mitigate the risk of electric shock, is considered an operating control. Operating controls are also referred to as regulating controls . Appendix A, Operating and Protective (Safety Critical) Control Functions, species control functions that are not con

41、sidered to result in a risk of re, electric shock, or injury to persons. 2.10 CONTROL, PROTECTIVE A device or assembly of devices, the operation of which is intended to reduce the risk of re, electric shock, or injury to persons during normal and reasonably anticipated abnormal operation of the appl

42、iance. For example, a thermal cutout/limiter, or any other control/circuit relied upon for normal and abnormal conditions, is considered a protective control. Protective controls are also referred to as limiting controls or safety controls and are investigated under normal and single-fault condition

43、s. Appendix A species control functions that are considered to result in a risk of re, electric shock, or injury to persons. 2.11 ELECTRONIC COMPONENT A part in which electrical conduction is achieved principally by electrons moving through a vacuum, gas or semiconductor. A metal oxide varistor (MOV

44、) is considered to be an electronic component, but neon indicators are not.

45、RONIC DISCONNECTION The de-energizing of a load within an appliance by an electronic device of a circuit. No electro-mechanical component having an air gap, such as a switch, contactor or relay is used to de-energize the load. IEC This denition is reproduced from IEC 60335-1, Ed. 5.1 b:2013 with per

46、mission of the American National Standards Institute (ANSI) on behalf of the International Electrotechnical Commission.

47、e equipment that may otherwise present a risk of electric shock; c) Retards propagation of ame initiated by electrical disturbances occurring within.

48、HOUT PERMISSION FROM UL 2.14 FUNCTIONAL PART A part other than an enclosure or cabinet used to maintain the intended relative physical position of xed or moving parts, or maintain the integrity of the structure. 2.15 GROUNDING, FUNCTIONAL Grounding of a point in an appliance which is necessary for a

49、 purpose other than safety. 2.16 IGNITION SOURCE Any high-voltage electrical component not located within an enclosure. 2.17 MAXIMUM OPERATING CURRENT (MOC) The current resulting when an electric motor and adjustable speed drive or drive system are operated under any conditions such as maximum speed/maximum load, maximum speed/minimum load, minimum speed/minimum load, minimum speed/maximum load, including locked-rotor such that current to the motor/a
