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.
