31、SION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover household, industrial, and commercial sealing, wrapping, and marking equipment rated at 600 volts or less for use in unclassied locations in accordance with the National Electrical Code, NFPA 70, such as laminators, label makers/applicat

32、ors, stamping machines, taping machines, wrapping machines, shrink tunnels, bag sealers, bag tying machines, heat sealing irons, and vacuum packaging machines. 1.2 These requirements also cover cord-connected units with an integral cigarette lighter connector assembly, or a direct current (DC) input

33、 jack for being powered from a separate Vehicle Battery Adapter. 1.3 These requirements do not cover appliances and equipment that are covered by individual requirements that are separate from this standard, such as soldering irons, ink-jet printers, or photographic lm printers. 1.4 These requiremen

34、ts do not cover appliances and equipment that are intended for use in marine or aircraft. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory or approximate information. 2.2 Unless otherwise indicated, all voltage and current values

35、 mentioned in this standard are root-mean-square (rms), and all pressures are calculated in per square inch (psi). 3 Undated References 3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code

36、or standard. 4 Glossary 4.1 For the purpose of this standard the following denitions apply. 4.2 APPLIANCE COUPLER A single-outlet, female contact device for attachment to a exible cord as part of a detachable power-supply cord to be connected to an appliance inlet (motor attachment plug). 4.3 APPLIA

37、NCE INLET (MOTOR ATTACHMENT PLUG) A male contact device mounted on an end product appliance to provide an integral blade conguration for the connection of an appliance coupler or cord connector. 4.4 APPLIANCE (FLATIRON) PLUG An appliance coupler type of device having a cord guard and a slot congurat

38、ion specied for use with heating or cooking appliances. FEBRUARY 26, 2016 SEALING, WRAPPING, AND MARKING EQUIPMENT - UL 963 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 4.5 AUTOMATICALLY CONTROLLED APPLIANCE An appliance that complies wi

39、th one or more of the following conditions: a) The repeated starting of the appliance is independent of any manual control if, after one complete cycle of operation, a limit device or similar component opens the circuit; b) During any single preset cycle of operation, the motor is caused to stop and

40、 restart; c) When the appliance is energized, the initial starting of the motor may be intentionally delayed beyond intended, conventional starting; and d) For an appliance using a motor with a separate starting winding, during any single predetermined cycle of operation, automatic changing of the m

41、echanical load reduces the motor speed sufficiently to re-establish starting-winding connections to the supply circuit. 4.6 AUXILIARY CONTROL A control that is intended primarily for time, temperature, or pressure regulation under conditions of intended operation, and not for protection against over

42、load or excessive conditions resulting from abnormal operation. 4.7 BRANCH CIRCUIT That portion of the building wiring system beyond the nal overcurrent device on the power-distribution panel protecting the circuit to the eld-wiring terminals in a permanently connected unit or to the receptacle outl

43、et for cord-connected units. 4.8 CABINET Refers to a housing of a unit that prevents access to a part that involves a risk of injury to persons as a result of hazardous moving parts or hot parts. The use of a cabinet to prevent access to a part that involves a risk of re, electrical energy high curr

44、ent levels, or electric shock is permitted. 4.9 CIGARETTE LIGHTER CONNECTOR The male connector provided as part of a Vehicle Battery Adapter for insertion into a cigarette lighter receptacle. 4.10 CONTROL, AUTOMATIC ACTION A control in which at least one aspect is non-manual. 4.11 CONTROL, AUXILIARY

45、 A device or assembly of devices that provides a functional utility, is not relied upon as an operational or protective control, and therefore is not relied upon for safety. For example, an efficiency control not relied upon to reduce the risk of electric shock, re, or injury to persons during norma

46、l or abnormal operation of the end product is considered an auxiliary control. 4.12 CONTROL, MANUAL A device that requires direct human interaction to activate or rest the control. 4.13 CONTROL, OPERATING A device or assembly of devices, the operation of which starts or regulates the end product dur

47、ing normal operation. For example, a thermostat, the failure of which, a thermal cutout/limiter or another layer of protection would reduce the risk of electric shock, re, or injury to persons, is considered an operating control. 4.14 CONTROL, PROTECTIVE A device or assembly of devices, the operatio

48、n of which is intended to reduce the risk of electric shock, re or injury to persons during reasonably anticipated abnormal operation of the appliance.

49、 WITHOUT PERMISSION FROM UL 4.15 CONTROL, TYPE 1 ACTION The actuation of an automatic control for which the manufacturing deviation and the drift (tolerance before and after certain conditions) of its operating value, operating time, or operating sequence has not been declared and tested under this standard. 4.16 CONTROL, TYPE 2 ACTION The actuation of an automatic control for which the manufacturing deviation and the drift (tolerance before and after certain conditions) of its opera
