This third earth path causes damage unless the other two paths provide a better earth connection allowing surge energy to bypass the electronics When an antenna is located outside of a building and outside of an industrial plant environment external coax surge diverters are recommended to further minimize the effect of surge current in the inner conductor of the coax cable WX16 User Manual 69 Coax surge diverters have a gas discharge element which breaks down in the presence of high surge voltage and diverts any current directly to a ground connection A surge diverter is not normally required when the antenna is within a plant or factory environment as the plant steelwork provides multiple parallel ground paths and good earthing will provide adequate protection without a surge diverter 7 6 2 Connections to Other Equipment Surges can enter the wireless unit from connected devices via I O serial or Ethernet connections Other data devices connected to the wireless unit should be well grounded to the same ground point as the wireless unit Special care needs to be taken where the connected data device is remote from the wireless unit requiring a long data cable As the data device and the wireless unit cannot be connected to the same ground point different earth potentials can exist during surge conditions There is also the possibility of surge voltages being induced on long lengths of wire from nearby power cables Surge diver
