To avoid the accidental use of a non-permissible electronics module,
the terminal blocks are coded.
On the opposite side, you must code the electronics module accord-
ing to your sensor.
In the following illustration there is an example of a sensor coded
without Ex approval (coding pin in terminal 4).
In terminal 2 there is already a coding pin. This coding prevents the
two terminal blocks from being exchanged.

You must code your sensor according to the new electronics module
of your sensor.
