Guidelines for the Reference Conductor System in the Cabinet

Reference conductor system The cabinet contains different reference conductor systems that are connected to one another:  An unpainted earth reference plane must be installed on the floor of the cabinet as the common reference potential.  The reference conductor system for the following areas must be separated from one another:  Analog part (with point-to-point arranged reference conductors)  Digital part (with meshed reference conductors)  Power circuit (usually with point-to-point arranged reference conductors)  The galvanic coupling for the reference conductor system must be minimized.
