How To Use The Wiring Diagrams
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, e.g. x/2.
Together, this constitutes a component designation, e.g. 3/2.
At the end, list of components, where, with the help of the component designation, you can read off the name of the component, for example, 3/2 = light
switch.
List of type numbers
The list shows which type of component that respective type numbers refer to, for example, 3/x = switch, 6/x = electric motor, etc.
