See 10.4.4(c)(1).36A.2 Blade Secureness Test36A.2.1 Each blade and the grounding pin, if provided, shall withstand a direct pull of 20 pounds-force (89N) for 2 minutes without loosening
25、. The two blades tested together shall also withstand a direct pull of 20pounds for 2 minutes without loosening.36A.2.2 To determine whether a controller complies with the requirement in 36A.2.1, it is to be supportedon a horizontal steel plate with the blades projecting downward through a hole havi
26、ng a diameter sufficientonly to permit the blades to pass through it. A 20-pound (9.1-kg) weight is to be supported by each bladeand the grounding pin, if provided, in succession and then by the two blades tested together. In acontroller of nonrigid construction for example, a controller of soft mol
27、ded material the displacementof either blade shall not exceed 3/32 inch (2.4 mm) measured 2 minutes after removal of the weight.36A.3 Security of Input Contacts Test36A.3.1 The plug-in blades and the grounding pin shall not loosen to a degree that introduces a risk offire or electric shock as a resu
28、lt of the tests described in 36A.3.2 and 36A.3.3.36A.3.2 A controller is to be rigidly supported in the blades-up position. Each blade, in turn, is to beindividually subjected to a force of 30 pounds-force (133 N) applied gradually along the longitudinal axisof the blade in a direction towards the f
29、ace of the controller. The 30 pounds-force is to be maintained for1 minute.36A.3.3 The sample used in 36A.3.2 is to be retested by being positioned as described in 36A.3.2 andsubjecting both blades and the grounding pin, if provided, in combination, to a single applied force of 40pounds-force (178 N
30、) for 1 minute.36A.4 Security of Output Connectors Test36A.4.1 For a controller provided with wire-binding terminals as output connectors, a terminal or terminalstud shall not turn or cause stress on internal connections when subjected to the test of 36A.4.2.36A.4.2 The appropriate torque specified
31、in Table 36A.4 is to be applied for 10 seconds to the terminalsin a direction tending to tighten them. The terminals are then to be loosened fully.STANDARD NUMBER: UL 69 -9-UL COPYRIGHTED MATERIAL NOT AUTHORIZED FOR FURTHER REPRODUCTION ORDISTRIBUTION WITHOUT PERMISSION FROM ULTable 36A.4Tightening

34、(89 N) for 1 minute.36A.5.2 The force specified in 36A.6.1 is to be increased from 0 to 20 pounds-force (0 to 89 N) over aperiod of 5 seconds applied through the axis of a 1/2 inch (12.7 mm) diameter metal rod, having a flatcontact end with the edge rounded to a radius of 1/32 inch (0.8 mm) to elimi
35、nate sharp edges. The forceis then to be maintained at 20 pounds for 1 minute. The axis of the rod is to be perpendicular to thesurface under test. During the test, the controller is to rest on a flat surface in any convenient position,and is to be energized. Shock current between the enclosure and
36、earth, and between any parts of theenclosure between which such currents may exist, are to be monitored. The instrumentation used is to bethat described in 24.5.36A.5.3 Following the rod pressure test, the controller is to be subjected to the Dielectric VoltageWithstand Test, Section 27, and to an e

42、chnology equipment, battery chargers, etc.The construction, mechanical performance, and instruction requirements are derived from the Standardfor Class 2 Power Supplies, UL 1310 which addresses direct plug-in constructions.A definition of a direct plug-in controller is included to distinguish that t
43、hese requirements do not apply todirect plug-in power supplies that are detachable from the fence controller. The definition alsocontemplates indoor use only applications. Further requirement develop is needed to contemplate outdooruse applications.These requirements represent present practice.Copyr
