Pair Wiring with Overall Insulation For all field I O wiring the use of twisted shielded pairs with overall insulation is highly recommended This type of cable provides discrete insulation for each of the wires and an additional overall insulated covering that provides greater E M I immunity and protection to the shield as well S1400T Page 5 2 Section 5 Wiring Techniques 5 2 3 Grounding of Cable Shields DO NOT connect the cable shield to more than one ground point it should only be grounded at one end Cable shields that are grounded at more than one point or at both ends may have a tendency to induce circulating currents or sneak circuits that raise havoc with I O signals This will occur when the ground systems associated with multipoint connections to a cable shield have a high resistance or impedance between them and a ground induced voltage is developed for what ever reason i e man made error or nature produced phenomena 5 2 4 Use of Known Good Earth Grounds 3808 MVT TTs should only have one connection to earth ground This connection is provided via the Ground Terminal that is situated on the inside of the units Electrical Housing Since model 3808 MVT TTs are DC based systems grounding does not take into account AC power grounding considerations These units should be connected to earth ground when they are installed in areas that have frequent lightning strikes or are located near or used in conjunction with equipment tha
