20、 requirements apply to power-operated dispensing devices for petroleum products such as gasoline for use as motor fuel. Requirements for the installation and use of these dispensing devices are included in the Automotive and Marine Service Station Code, NFPA 30A, and the National Electrical Code, NF

21、PA 70. 1.2 These requirements apply to wiring methods used to install or interconnect such control equipment when the equipment is located directly on or within the housing of the dispensing device. These requirements do not apply to control equipment that may authorize, monitor, or interrupt operat

22、ion of a power-operated dispensing device. Such equipment includes panel mounted equipment located adjacent to the dispensing device, remote consoles located inside a permanent structure, and auxiliary equipment physically attached to the dispensing device or enclosed by the pedestal and housing. 2

23、General 2.1 Components 2.1.1 Except as indicated in 2.1.2, 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 this standard. 2.1.2 A component is not requi

24、red 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or characteristic not required in the application of the component in the product covered by this standard, or b) Is superseded by a requirement in this standard. 2.1.3 A component shall be used in accordance with its rating establi

25、shed for the intended conditions of use. 2.1.4 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 specied limits, and shall be used only un

26、der those specic conditions.

28、e of this standard the following denitions apply. 3.2 AIR GAP A minimum of 1 inch (25.4 mm) free air space provided between the planes of Division 1 or Division 2 hazardous locations and an unclassied area of a dispensing device. 3.3 BASE That part of the assembly which is intended to be secured to

29、the foundation on which the device will be installed. 3.4 CLASS I HAZARDOUS LOCATIONS Locations in which ammable gases or vapors are or may be present in the air in quantities sufficient to produce explosive or ignitable mixtures. For the purpose of these requirements, as applied to dispensing syste

30、ms of other than the overhead type, the following classied areas are further dened. Such areas for overhead type systems shall be as specied in the Automotive and Marine Service Station Code, NFPA 30A. The area of the dispensing system covered by these requirements is the envelope dened by the maxim

31、um outer dimensions. a) Class I, Group D, Division 1 1) The area within a dispenser housing up to 4 feet (1.2 m) vertically above the base, except for that area dened as Division 2 or unclassied. 2) Any area within a nozzle boot. b) Class I, Group D, Division 2 1) Areas within a dispenser housing ab

32、ove the Division 1 area. 2) The area surrounding the dispenser housing within 18 inches (46 cm) horizontally in all directions from the Division 1 area located within the housing. 3) The area within 18 inches horizontally, in all directions from the opening of a nozzle boot not isolated by a vapor-t

33、ight partition, except that the area is not required to be extended around a 90-degree or greater corner. See Figures 3.1 and 3.2 for an illustration of Class I hazardous locations.

36、FOR FURTHER REPRODUCTION OR DISTRIBUTION WITHOUT PERMISSION FROM UL 3.5 DISPENSER, REMOTE-CONTROL TYPE A dispensing device that does not contain a power- operated pump as part of the assembly, and which is intended for connection to a uid piping system containing the power operated pumps at a remote

37、 location. Also commonly identied as a dispenser. 3.6 DISPENSER, SELF-CONTAINED A dispensing device that includes a power operated pump as part of the assembly. Also commonly identied as a pump or suction dispenser. 3.7 DISPENSING DEVICE A product consisting of a meter, motor, or uid control, and an

38、 area for storing a hose nozzle valve with or without a pump. 3.8 ELECTRICAL CIRCUITS a) High-Voltage Circuit A circuit involving a potential of not more than 600 volts and having circuit characteristics in excess of those of a low-voltage or Class 2 circuit. b) Low-Voltage Circuit A circuit involvi

39、ng a potential of not more than 30 volts alternating- current (rms) (42.4 volts peak or direct current) and 1) Supplied by a Class 2 transformer, or by a battery, by a battery and xed impedance, or by a transformer and xed impedance each of which, as a unit, is in compliance with what is required fo
