29、he requirements for that component. See Appendix A for a list of standards covering components 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 com

30、ponent in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance with its rating established for the intended conditions of use. 2.1.4 Specic components are incomplete in construction features or restricted in perfor

31、mance capabilities. Such components are intended for use only under limited conditions, such as certain temperatures not exceeding specied limits, and shall be used only under those specic conditions. 2.2 Units of measurement 2.2.1 Values stated without parentheses are the requirement. Values in par

32、entheses are explanatory or approximate information. 2.2.2 Unless otherwise indicated, all voltage and current values mentioned in this standard are root-mean-square (rms). 2.3 Undated references 2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shall b

33、e interpreted as referring to the latest edition of that code or standard. MAY 14, 2004 COMMUNICATIONS-CIRCUIT ACCESSORIES - UL 1863 6UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3 Glossary 3.1 For the purpose of this standard the followi

34、ng denitions apply. 3.2 COMMON MODE VOLTAGE When applied to telecommunications leads, this term refers to the voltage between any conductor or connection point and earth ground. Also referred to as Longitudinal Voltage. 3.3 DIFFERENTIAL MODE VOLTAGE When applied to telecommunications leads, this ter

35、m refers to the voltage between any conductors or connection points excluding those connected to earth ground. Also referred to as Metallic Voltage. 3.4 ELECTRICAL ENERGY HIGH-CURRENT LEVELS (POWER SUPPLIES) The capability for damage or injury to persons (other than by electric shock) from available

36、 electrical energy is considered to exist when, between a live part and an adjacent dead-metal part or between live parts of different polarity, there exists a potential of 2 volts or more and either: a) An available continuous power level of 240 volt-amperes or more or b) A reactive energy level of

37、 20 joules or more. For example, a tool (or other metal) short-circuiting a component is capable of posing a risk of re, electric shock, or injury to persons (burns) when enough energy is available at the component to vaporize, melt, or more than warm the metal. 3.5 ENCLOSURE The word enclosure refe

38、rs only to parts that house or cover: a) Uninsulated live parts that involve a risk of electric shock or b) Parts that involve a risk of re, electrical energy/high-current levels, or injury to persons. An enclosure may be an integral part of a component, a separate item or part of an outer cabinet.

39、3.6 FIXED OR STATIONARY EQUIPMENT Equipment that is not easily moved, and is intended to be moved from one place to another only when de-energized. Fixed equipment is usually fastened or secured to the building. 3.7 GROUND A conducting connection, whether intentional or otherwise, between electrical

40、 circuits or electrical equipment and either the earth or some conducting body that serves in place of the earth. 3.8 GROUNDING The act of establishing a conductive connection, whether intentional or otherwise, between an electrical circuit or electrical equipment and earth. 3.9 LONGITUDINAL VOLTAGE

41、 See 3.2, Common Mode Voltage. 3.10 METALLIC VOLTAGE See 3.3, Differential Mode Voltage. 3.11 NETWORK OPERATING VOLTAGES Telecommunications networks normally operate at voltages of 56.5 volts DC or less, unless the source impedance is above the range of 300 1600 ohms. For equipment connected to a si

42、ngle tip and ring pair, alerting and test voltages higher than 56.5 volts are generally intermittent and will be present over less than 1 percent of the usage of the MAY 14, 2004 COMMUNICATIONS-CIRCUIT ACCESSORIES - UL 1863 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION OR DISTRIBU

43、TION WITHOUT PERMISSION FROM UL equipment. Some telecommunications equipment, such as PBX and Key systems, may have a greater percentage of usage or operate at a higher voltage (such as T type lines). Maximum ring voltages may not exceed 200 volts peak-to-ground or 300 volts peak-to-peak. 3.12 NONPR

44、OTECTED SIDE The portion of the loop circuit that rests on the primary side of a telephone protector installed by the operating telephone company. The fault current limitation is subject to the breakdown voltage characteristics of the primary protector and its coordinated fusing system (e.g., fuse l

45、ink or bridle wire) with which the protector is intended to be used. 3.12 revised May 14, 2004 3.13 PORTABLE EQUIPMENT Equipment that is easily moved and can be carried or conveyed by hand. Portable equipment is usually hand-held or hand-supported. 3.14 PRODUCT This term refers to all types of telep

46、hone equipment and appliances likely to be used in residential, commercial, and industrial environments. 3.15 PROTECTED SIDE Refers to that portion of the loop circuit that is connected to the secondary or output side of the primary telephone protector and is limited to short and long term current r

47、equirements for secondary protectors. 3.16 RISK OF ELECTRIC SHOCK The risk that a person encounters when exposed to live uninsulated parts of a product that have a voltage and current sufficient to cause an electric shock, as dened in Accessibility and Electric Shock, Section 8. 3.17 RISK OF FIRE Th

48、e risk that a re may occur as a result of equipment or component failure or the application of specied test conditions. A risk of re is considered to exist at any component unless an investigation of the circuit delivering power to that component complies with the power limitations criteria cited in

49、 this standard. 3.18 RISK OF INJURY TO PERSONS A risk of injury to persons is considered likely to occur when one or more of the following conditions exist: a) Sharp edges, burrs, or projections are present that can cause injury during use or servicing. b) The stability of a product is such that it can cause injury to persons. See Stability, Section 22. c) Uninsulated live parts involving a risk of electrical-energy/high-current levels are accessible to personnel. See Accessi
