Mechanical Configuration of an Automation System with SIMATIC S7 Ex Modules 1-14 Terminal board Fresh water Main EB Heating Hot water Connection for TN system Main ground connector Antenna system (Secondary equipotential bonding for automation system) System surface Power supplies SECONDARY EQUIPOTENTIAL BONDING (e.g. storey distribution board) Telecommunication system Heating Internal gas pipe Lightning protection system Insulator Drain Foundation ground Earth termination MAIN EQUIPOTENTIAL BONDING Fig. 1-9 Main and secondary equipotential bonding in accordance with VDE I/O Modules with Intrinsically-Safe Signals C79000-G7076-C152-04
Main equipotential bonding Additional equipotential bonding 380 V I/O Modules with Intrinsically-Safe Signals C79000-G7076-C152-04 This interconnects the following conductive elements by the EB conductor on the EB bus: APA = 0.5 x APE-main – Main PE conductor – Main ground conductor – Earth termination – Main water pipes – Main gas pipes – Other metal piping systems – Metal structural elements of the building (if possible) – Power and information system cables extending beyond the building, via lightning conductor. This interconnects the following conductive elements by the EB conductor on the EB bus: – All ”extraneous conductive elements” such as structural elements, supports, containers, piping (these themselfs can form EB conductors), APA = 0.5 x APEmax (A = cable cross section) from the distrib. board. – Elements of stationary electrical apparatus which are accessible to simultaneous contact when it is connected to PEN (otherwise a PE connection is sufficient), APA = 0.5 x APE of both items of apparatus.
