33、RODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover automatic ice makers designed for connection to alternating-current circuits rated not more than 600 volts. 1.2 These requirements apply to unitary and remote ice makers. For the purpose of this st

34、andard, an ice maker includes a means for automatically manufacturing and harvesting ice in cube, ake, or other readily usable form, with or without provision for storage or means of dispensing ice. 1.3 Self-contained ice makers covered by these requirements employ hermetic refrigerant motor-compres

35、sors and air- or water-cooled condensers. 1.4 These requirements do not apply to ice makers of the tray type, ice vending machines, or to ice makers and ice maker kits used in household refrigerators and freezers. 1.5 Requirements for the installation of ice makers are included in the National Elect

38、unit” are used interchangeably and refer to all ice makers or any part thereof covered by this standard unless specically noted otherwise. 2.4 Undated references 2.4.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the

39、latest edition of that code or standard. 3 Glossary 3.1 For the purpose of this standard, the following denitions apply. 3.2 ACCESSORY An optional electrical device or other component intended for installation in or connection to an ice maker, for the purpose of modifying or supplementing the functi

40、ons of the ice maker. It may be factory-installed or intended for installation by the user or service personnel. 3.3 BARRIER A partition for the: a) Insulation or isolation of electrical circuits, b) Isolation of electrical arcs, or c) Isolation of moving parts or hot surfaces. 3.3.1 CAPILLARY TUBE

41、Device made of tubing with an outer diameter of less than 3/16 in. (4.7 mm) and used to reduce the pressure of the refrigerant between the condenser and evaporator. It also regulates the refrigerant ow. 3.3.1 added September 30, 2011 3.4 CIRCUITS, ELECTRICAL a) High-Voltage A circuit involving a pot

42、ential of not more than 600 volts and having circuit characteristics in excess of those of a low-voltage circuit. b) Low-Voltage (Class 1) A circuit involving a potential of not more than 30 volts ac (42.4 volts peak) and an output of not more than 1000 volt-amperes. c) Low-Voltage (Class 2) A circu

43、it involving a potential of not more than 30 volts ac (42.4 volts peak) or 30 volts dc, and supplied by: 1) A primary battery, 2) A National Electrical Code, ANSI/NFPA 70, standard Class 2 transformer, or 3) A combination of a transformer and xed impedance which, as a unit, complies with all perform

44、ance requirements for a Class 2 transformer. SEPTEMBER 30, 2011 ICE MAKERS - UL 563 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3.4.1 COMPONENT A device or fabricated part of the appliance covered by the scope of a safety standard dedic

45、ated to the purpose. When incorporated in an appliance, equipment otherwise typically eld installed (e.g. luminaire) is considered to be a component. Unless otherwise specied, materials that compose a device or fabricated part, such as thermoplastic or copper, are not considered components. 3.4.1 ad

46、ded September 30, 2011 3.5 DESIGN PRESSURE The maximum allowable working pressure for which the ice maker is designed. 3.6 ELECTRIC GRID A hot wire assembly designed to cut slab ice into cubes. 3.7 ENCLOSURE That part of an ice maker that by itself or in conjunction with barriers: a) Renders inacces

47、sible all or any part of the unit that may otherwise present risk of electric shock, b) Reduces the risk of contact with parts that may cause injury to persons, and/or, c) Prevents propagation of ame initiated by electrical disturbances occurring within the unit. A unit cabinet that serves as sole e

48、nclosure for ignition sources is considered to be a group 1 enclosure. Separate enclosures located within or mounted on the outer surface of the unit cabinet are considered group 1 enclosures if they serve as a sole enclosure for ignition sources. Enclosures not serving as an ultimate enclosure for

49、ignition sources are considered to be group 2. 3.8 FUNCTIONAL/STRUCTURAL PART A part used to maintain the intended relative physical position of xed or moving parts, or maintain the integrity of the structure. A cabinet liner that supports an electrical component is considered to be a functional part. 3.9 HARVEST CYCLE The function of removing or separating the manufactured ice from the evaporator. 3.10 ICE MAKER (CYCLIC) An automatic ice maker that has separa
