Terminals shall be represented and identified by the terminal designations marked on the device or, as with a dual-in-line package or an electronic tube, assigned by the manufacturer or by convention. Common rules for connection diagrams, tables and lists 2. Figure 3 shows an example where the diagram shows the conductors grouped in two cable bundles, —W1 and —W2. The notation in the remarks column indicate that a second conductor or device is connected to the same terminal.


The number fre cores of a cable is noted in a column, adjacent to the cable number and the spare cores in the last column on the same line. Single-line representation has been used and the information on the individual connections has been supplemented with information on the kind of current and voltage. Unit connection diagrams and tables 3. On this page you get an overview of standards on electrical documentation, which are covered in the book “Electrical documentation according to standards”.
