The standard may not use all types of thesedeviations.D1 - These are deviations which are based on basic safety principles and requirements, eli

10、mination ofwhich would compromise safety for U.S. consumers and users of products.D2 - These are deviations based on safety practices. These are deviations for IEC requirements that maybe acceptable, but adopting the IEC requirements would require considerable retesting or redesign on themanufacture

11、rs part.DC - These are deviations based on the component standards and will not be deleted until a particularcomponent standard is harmonized with the IEC component standard.DE - These are deviations based on editorial comments or corrections.DR - These are deviations based on the national regulator

12、y requirements.Each national difference contains a description of what the national difference entails. Typically one of thefollowing words is used to explain how the text of the national difference is to be applied to the base IECtext:Addition / Add - An addition entails adding a complete new numbe

13、red clause, subclause, table, figure,or annex. Addition is not meant to include adding select words to the base IEC text.Deletion / Delete - A deletion entails complete deletion of an entire numbered clause, subclause, table,figure, or annex without any replacement text.Modification / Modify - A mod

14、ification is an altering of the existing base IEC text such as the addition,replacement or deletion of certain words or the replacement of an entire clause, subclause, table, figure,or annex of the base IEC text.FEBRUARY 14, 2017 NATIONAL DIFFERENCES FOR UL 60730-2-9 3UL COPYRIGHTED MATERIAL NOT AUT

39、ng Clauses to the Part 2:14.102ADV.1 The following is applicable to controls classified under 6.7.103BDV.14.102ADV.2 A control (SHTP) is to be installed in a 152 by 152 by 152 mm (6 by 6 by 6inch) box constructed of 12.7 mm (1/2 inch) thick GradeADfirplywood. A control (SHTP)with measurement thermoc

40、ouples attached is to be inserted through an open hole in thebox such that the back of the body of the device is flush with the outside of the box. Theopen hole in the box is to have dimensions only as large as necessary to accommodatethe protector (snug fit). The open hole is to be located in the s

41、ide of the box such that it iscentered horizontally and the top of the open hole is 25.4 mm (1 inch) below the top of thebox.14.102ADV.3 The box is to be completely filled (flush with the top of the box) withexpanding polyurethane foam. A 12.7 mm (1/2 inch) thick plywood top is to be provided onthe

42、box.14.102ADV.4 A control (SHTP) is to be connected to two separate supply sources. Onesupply source is to be adjusted to rated voltage and connected through the integralthermal protector across the maximum rated lamp load. The other supply source is to beconnected to the SHTP heater and adjusted to

43、 the maximum voltage that will not result inthe integral thermal protector cycling within 7-1/2 hours (this usually will result inoperating the heater at less than rated voltage). If the thermal protector will not trip within7-1/2 hours at rated voltage and under the test conditions specified, two 1

44、02 by 102 by 44.5mm square (4 by 4 by 1-3/4 in) trade size metal outlet boxes are to be secured to the woodtest box over the base of the SHTP as shown in Figure 14.102ADV.1. A length of 2.0 mm2(12 AWG), Type THHN wire is to be arranged as shown and secured in place by RTVsealant. With the supply vol

45、tage to the SHTP heater at rated voltage, the box heaterconductors are to be energized by a low voltage source of supply with the supply adjustedto the maximum current that will not result in the thermal protector cycling within 7-1/2hours. The lamp load is to be located such that any heat produced

46、by it will not affect theoperation of the thermal protector. Temperature measurements are to be made at variousparts of the product using methods described in Clause 14.FEBRUARY 14, 2017 NATIONAL DIFFERENCES FOR UL 60730-2-9 7UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBU
