34、ION WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover energy management equipment and associated sensing devices rated 600 volts or less and intended for installation in accordance with the National Electrical Code, NFPA 70. 1.2 This equipment energizes or de-energizes ele

35、ctrical loads to achieve a desired use of electrical power. The equipment is intended to control electrical loads by responding to sensors or transducers monitoring power consumption, by sequencing, by cycling the loads through the use of preprogrammed data logic circuits, or any combination thereof

36、. Devices responding to signals from a utility company may receive the signals over the power lines or as radio signals. 1.3 These requirements also cover equipment intended for connection only to a low-voltage circuit of limited power supplied by a Class 2 transformer. 1.4 These requirements do not

37、 cover switching devices operated by a mechanical or electromechanical clock mechanism to energize or de-energize loads. These requirements do cover electronic clock operated energy management equipment. 1.5 Controls intended to be installed in air handling spaces or in other environmental air space

38、 (plenums) are covered under the scope of this standard. 2 Components 2.1 Except as indicated in 2.2, a component of a product covered by this standard shall comply with the requirements for that component. See Appendix A for a list of standards covering components used in the products covered by th

39、is standard. 2.2 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or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.3 A component shall be use

40、d in accordance with its rating established for the intended conditions of use. 2.4 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 spec

41、ied limits, and shall be used only under those specic conditions.

42、 value in other units in parentheses, the rst stated value is the requirement. 3.2 Unless otherwise indicated, all voltage and current values mentioned in this standard are root-mean-square (rms). 4 Undated References 4.1 Any undated reference to a code or standard appearing in the requirements of t

43、his standard shall be interpreted as referring to the latest edition of that code or standard. 5 Glossary 5.1 For the purpose of this standard the following denitions apply. 5.2 CLASS 2 SYSTEM A circuit, transformer, or power source having energy- and voltage-limiting characteristics as described in

44、 the National Electrical Code, ANSI/NFPA 70. 5.3 CONTROLLED ENVIRONMENT An environment relatively free of contaminants. A controlled environment may also be provided by means of a totally closed, gasketed enclosure or the equivalent. 5.4 DEAD-CASE-MOUNTED SEMICONDUCTOR A semiconductor, such as a tri

45、ac or silicon-controlled rectier, employing an integral metal tab or stud that is insulated from live parts. 5.5 FIELD-WIRING TERMINAL A wiring terminal on permanently-connected equipment to which supply connections are made when the equipment is installed in the eld. 5.6 ISOLATED LIMITED-ENERGY LOW

46、-VOLTAGE CIRCUIT A circuit (also hereafter referred to as a low-voltage circuit) involving a potential of not more than 42.4 volts peak supplied by one of the following: a) An energy-limiting Class 2 transformer; b) A non-energy-limiting Class 2 transformer and an overcurrent protective device. The

47、protective device is: 1) Not to be of the automatic reclosing type; 2) To be trip-free from the reclosing mechanism; and 3) Not to be readily interchangeable with a device of a different rating; c) A combination of an isolated transformer secondary winding and a xed impedance that complies with all

48、the performance requirements for an energy-limiting Class 2 transformer or power source; d) A dry-cell battery having output characteristics not greater than those of an energy-limiting Class 2 transformer or power source; or e) A combination of a rechargeable battery and a xed impedance that compli

49、es with all of the performance requirements for an energy-limiting Class 2 transformer or power source.
