Mechanical coding of the electronic modules
Electronic modules are supplied with a two-part coding element.
When an electronic module is plugged into a base module for the first time, one part of the
coding element remains on the electronic module, while its counterpart is fixed on to the
base module. This is how the base module is coded.
The coding element is designed to help prevent plugging errors (e.g. when exchanging an
electronic module). Once a base module has been coded, it will only take electronic mod-
ules with the same mechanical coding.
The coding is identified by a letter and a colour. Codings with the same letters are mechan-
ically identical and are distinguished through a different colour.
