6.4 Performing Pin Coding

Pin coding prevents confusion when using multipole terminals, e.g. in the event of removal and later

re-insertion of the multipole plug. The correct terminal can always be assigned to the multipole plug

via the coded pins. Tip: perform pin coding for all multipole terminals now, even if you do not wish to

use all multipole terminals at this point. This means that you do not subsequently have to perform pin

coding for the multipole terminals that are not currently in use.

Code every multipole terminal according to the following procedure.

1. Insert the coding tab of the coding element into the

pin that is to be coded parallel to the conductor

axis.

2. Remove the coding tab from the coding element by

snapping it off.

3. Remove the key at the rear of the cable entry in the

multipole plug into which the code pin is to be

inserted during connection to the Cluster Controller.

Code the pins correctly

When selecting the pins to be coded, ensure that different pins are coded for each terminal and

for each pin row.
