33、cal 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 card, currency, and token-operated devices intended to be
34、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 requirements. 2 Glossary 2.1 For the purpose of this standard, th
35、e following denitions apply. 2.1.1 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 sensors. 2.1.1 added December 5, 2014 2.1.2 ADJUSTABLE S
36、PEED 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. 2.1.2 added December 5, 2014 2.2 APPLIANCE Denotes all
37、 coin, 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. 2.3 BARRIER A partition for isolating high-voltage e
38、lectrical components, separating ignition sources from ammable materials, isolating moving parts and protection of wiring. 2.4 CABINET The part of the equipment that provides physical protection to insulated wiring, enclosures, moving parts, motors, enclosed electrical parts, tubing or other parts t
39、hat may cause injury to persons. 2.5 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
40、 30 volts AC rms, 42.4 volts DC or AC peak. DECEMBER 5, 2014 COIN AND CURRENCY CHANGERS AND ACTUATORS - UL 756 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL c) Power-Limited A circuit whose output is limited as specied in Power-Limited Ci
41、rcuits, Section 60. d) Class2Acircuit in which the voltage and power limitations are in accordance with the Class 2 requirements of Table 60.1 for AC circuits and Table 60.2 for DC circuits. e) Class3Acircuit in which the voltage and power limitations are in accordance with the Class 3 requirements
42、of Table 60.1 for AC circuits and Table 60.2 for DC circuits. 2.5 revised December 5, 2014 2.6 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 instal
43、led (e.g. luminaire) is considered 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
44、 components are intended for use only under specic, limited conditions, such as certain temperatures not exceeding specied limits. 2.7 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, th
45、e failure of which a thermal cutout/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 species control functions that are not considered to result in a risk
46、of re, electric shock, or injury to persons. 2.7 revised December 5, 2014 2.8 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
47、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
48、s. Appendix A species control functions that are considered to result in a risk of re, electric shock, or injury to persons. 2.8 revised December 5, 2014 2.9 ENCLOSURE The part of the appliance that does one or more of the following: a) Isolates ignition sources; b) Renders inaccessible all or any p
49、art(s) of the equipment that may otherwise present a risk of electric shock; c) Retards propagation of ame initiated by electrical disturbances occurring within. 2.10 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.
