The most effective grounding method is direct connection to earth ground with minimal impedance. For approval selection code “1”, to maintain Intrinsic safety of system connect conductor to earth ground so that it has less than 1 Ohm to earth ground. See ANSI/ISA RP12.06.01 Installation of Intrinsically Safe Systems for Hazardous (Classified) Locations for guidance on installation of intrinsically safe apparatus and systems. Pipe connection Wafer style (Size: 25 to 100 mm (1 to 4 inches)) Flange style (Size: 2.5 to 200 mm (0.1 to 8 inches)) Length of straight pipe Required straight pipe length clearance on the upstream side and the downstream side, while installing the detector. Upstream side A minimum 5D straight pipe length is required. A minimum 10D straight pipe length is required if a diffuser/valve/pump is installed upstream side. Downstream side 2D straight pipe length is recommended.
