How to use the wiring diagram

The descriptions below apply in general to all wiring diagram information, although not all sections are necessarily contained in this information.

A. Component designation

Every component has a component designation that consists of two parts.

The first part is a type number that describes the type of component in question, for example 3/xx.

The second part of the designation is a serial number, for example, x/2.

Combined these give a component designation, for example, 3/2.

There is a list of components at Component ID List, where, with the help of the component designation, you can read off the name of the component, for
example, 3/2 = light switch.  See: Diagrams/Diagram Information and Instructions/Diagram Legend
