The Tankvision Gauge Link is double insulated, and thus does not require connection of a protective earth for safety reasons. An earth terminal is included in the mains supply connector for EMC purposes. This should be connected to the earth/equipotential conductor of the supply. Endress+Hauser... - Page 13 Both the Enraf Bi-Phase Mark and SAAB Rosemount TRL/2 fieldbuses are galvanically isolated and offer over voltage protection commensurate with the original gauge manufacturers’ equipment. The Tankvision Gauge Link will be supplied as two different versions, one supporting the Enraf Protocol and the other supporting the SAAB Rosemount TRL/2 protocol. Endress+Hauser...
