29、OT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover antenna rotators intended for household and commercial use on supply circuits in accordance with the National Electrical Code, NFPA 70. 1.2 An antenna rotator generally

30、 consists of: a) A mast-mounted (generally outdoors), motorized drive unit that rotates the antenna to the desired receiving azimuth, b) An indoor-located (usually near television- or radio-receiving equipment) user-operated control unit that delivers operating power and direction signals to the dri

31、ve unit, and, c) A length of multiple-conductor Class-2 circuit cable to electrically interconnect the drive unit and the control unit. Some antenna rotating units may control antenna elevation separately or in addition to azimuth. In some cases, the drive unit may be located indoors. 1.3 The power

32、used to drive the motor of an antenna rotator is derived from a circuit complying with Class 2 limitations in accordance with Article 725 of the National Electrical Code, ANSI/NFPA 70. 1.4 These requirements do not cover systems that use a stationary antenna and change or rotate the receiving patter

33、n by electronic or switching means. Such systems are covered by the Standard for Audio-Video Products and Accessories, UL 1492. 2 General 2.1 Components 2.1.1 A component shall be used in accordance with its rating established for the intended conditions of use. See Appendix A for a list of standard

34、s covering components generally used in the products covered by this standard. 2.1.2 A component is not required to comply with a specic requirement that: a) Involves a feature or characteristic not required in the application of the component in the product covered by this standard, or b) Is supers

35、eded by a requirement in this standard. 2.1.3 Specic components are incomplete in construction features or restricted in performance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only und

36、er those specic conditions. NOVEMBER 9, 2004 ANTENNA ROTATORS - UL 150 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanato

37、ry or approximate information. 2.2.2 Alternating-current electrical measurements are in rms units unless otherwise stated. 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition o

38、f that code or standard. 3 Glossary 3.1 For the purpose of this standard the following denitions apply. 3.2 ACCESSIBLE PART A part located so that it can be contacted by means of a probe. See Accessibility of Parts, Section 10. 3.3 ADJUSTABLE CONTROL A control provided for making adjustments necessa

39、ry to render the product capable of performing its intended functions. 3.4 CONTROL UNIT A user-operated, indoor-mounted unit with total output limited to Class 2 levels (see 1.3), the primary function of which is to deliver power to and control a drive unit. 3.5 DRIVE UNIT A mast-mounted (generally

40、outdoors), motorized unit that may be user-installed and is intended to position an antenna and that requires an energy source limited to Class 2 levels. See 1.3. 3.6 FIBER Vulcanized ber. 3.7 INSULATION, BASIC The insulation necessary for the intended functioning of the product and for basic protec

41、tion to reduce the risk of electric shock. 3.8 INSULATION, REINFORCED An improved basic insulation with mechanical and electrical qualities such that it, in itself, provides the same degree of protection to reduce the risk of electric shock as an insulation system comprised of both basic insulation

42、and supplementary insulation. 3.9 INSULATION, SUPPLEMENTARY An independent insulation provided in addition to the basic insulation to provide protection to reduce the risk of electric shock in case of electrical breakdown of the basic insulation. 3.10 MAJOR ENCLOSURE PART A part of the enclosure tha

43、t: a) Forms more than 50% of any one surface, and b) Is needed to comply with the requirements to 1) Reduce the risk of re, electric shock, or injury to persons, or 2) Reduce the risk of mechanical damage to internal parts. 3.11 MINOR DIMENSION OF OPENING The diameter of the largest sphere that can

44、pass through the opening. NOVEMBER 9, 2004 ANTENNA ROTATORS - UL 150 8UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3.12 OPERATING CONTROL A control, usually a knob, pushbutton, or lever, provided to enable the user to cause the product to

45、 perform its intended function, without the use of tools, when the product is in normal operating condition. 3.13 ORDINARY TOOLS Flat-bladed and cross-head screwdrivers, nut-drivers, pliers, and the like. 3.14 POWER-SUPPLY CORD The cord provided to connect the control unit to the supply circuit. 3.1

46、5 SUPPLY CIRCUIT The branch circuit supplying electrical energy to the product. 3.16 UNINSULATED PART A part that is bare (without insulation) or has insulation that is not suitable for the operating conditions (such as potential and temperature) involved. 3.17 USER SERVICING User servicing includes

47、: a) Fuse Replacement of a fuse other than: 1) A fuse intended to be soldered in place. 2) A fuse not readily perceptible to the user. A fuse is not readily perceptible if it is located within a chassis, compartment, or enclosure within the overall product that makes the fuse invisible to the user.

48、If the enclosure has a cover, it is to be one that: i) Does not need to be opened or removed in normal operation or user servicing, ii) Can be opened or removed only with a tool, and iii) Is prevented from being discarded. A fuse is readily perceptible if it is recognizable during normal operation o

49、r user servicing, either visually or by touch; or if the fuse is indicated, either on the product or on literature packed with it. 3) A clipped-in-type fuse that is within a compartment provided with the marking described in 53.4.1. b) User Adjustment Adjustment of a marked adjustable control or an adjustable component if the adjustment can be accomplished: 1) By using an ordinary tool, 2) With the product in operation, and 3) Without defeating an interlock. c) Unmarked Adjustment A
