Connection labels
Connection labels are symbols that display information specific to the
cabling of the device. This specificity also
means that they can be inserted outside a scheme drawing or a line drawing
(drawings of terminal strips, reports or 2D layouts).
A connection label is a representation of a device in terms of connections.
A component that does not have a manufacturer
part associated with it cannot be represented by a connection label.
Connection labels have specific attributes
which propagate the material terminals numbers, the equipotential numbers
or wire numbers, the cable core and cable marks, the destination symbol
marks, and the position of the symbols in the scheme drawings.
The connection labels are associated with the scheme symbols by their
mark (the same mark as the symbols) and must be associated with a manufacturer
part.

A connection label can be the representation of a manufacturer part
(single device), a component (one or several symbols, one or several manufacturer
parts). This distinction is made during insertion.
