Route cable in grounded metal conduit, separate from other cables. 2. Verify that all system components are installed in accordance with instructions. 3. Connect all cable shields to the SITRANS LT500 shield connections. Avoid differential ground potentials by not connecting cable shields to ground (earth) anywhere else. 4. Keep exposed conductors on shielded cables as short as possible to reduce noise...
