Performing Pin Coding
Pin coding prevents confusion when using multipole connectors, e.g. in the event of removal and
later re-insertion of a multipole plug. Using the coded pins, you can be sure of inserting a multipole
plug into the correct terminal. Tip: perform pin coding for all multipole connections now, even if you
do not wish to use all multipole connections at this point. Then you will not need to perform pin
coding later for the multipole connections that you are not currently using.
Code the pins correctly
When selecting the pins to be coded, be sure to code different pins for each terminal and for
each pin row.
