6.4 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.
Procedure:
1. Insert one of the coding tabs on the coding
element, parallel to the conductor axis, into the
pin to be coded.
2. Remove the coding tab from the coding element
by snapping it off.
3. On the multipole plug, remove the key from the
conductor entry that will receive the coded pin
when connected to the Cluster Controller.
6.5 Preparing Connection Cables for Connection to
Multipole Plugs
Always proceed as follows to prepare connection cables for connection to multipole plugs.
