EMERSON KJ4001X1-BE1 Analog output module

Content introduction

When the surge arrester is not properly grounded, its response time will be delayed and a higher clamp voltage than that of the surge arrester will be impressed across the equipment being protected. This can also be expected if the earth ground connection for the surge arrester contains loops or sharp bends or is not properly bonded to the earth electrode subsystem. To overcome this problem, stranded copper wire specified in accordance with Article 280 of the NEC® must be used to make the ground connection unless other specifications are provided by the manufacturer of the surge arresters. Figures 3-25 and 3-26 show the surge arresters installed to ensure the best direct route to ground thereby minimizing the lead inductance(s) and ensure the firing of the surge arresters. For best results exothermic welds should be used for bonding to the earth electrode subsystem. UL–approved pressure connectors are suitable for aboveground bonds.
