To prevent 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.
To allow easier handling, the coded pins are mounted on a plastic
plate. Two of these mounting supports are enclosed with the electron-
ics module.
In the following illustration there is an example of a sensor coded
without Ex approval (coding pin in terminal 4).
There is already a coding pin in terminal 2. This coding prevents the
two terminal blocks from being exchanged.
