1 Scope This Part of GB 3836 contains the details of apparatus, systems and installation practice for use with the Fieldbus Intrinsically Safe Concept (FISCO). It is based on the concepts of Manchester encoded, bus powered systems designed in accordance with GB/T 16657.2 which is the physical layer standard for Fieldbus installations. The constructional and installation requirements of FISCO apparatus and systems are determined by GB 3836.4, GB 3836.15, and GB 3836.18, except as modified by this standard. Part of a Fieldbus device may be protected by any of the methods of explosion protection listed in GB 3836.1, appropriate to the zone of intended use. In these circumstances, the requirements of this standard apply only to that part of the apparatus directly connected to the intrinsically safe trunk or spurs.
