Preventing Connector Interchanges through Coding

Overview
You can order a connector set with coding profiles and coding tabs as an
accessory for the C7-613 (see accessories in Section 1.2).
Caution
!
Your C7-613 control system may be damaged if you unintentionally interchange
the connectors.
You should therefore prevent such interchanges by coding your connectors.
Coding connectors
Use the coding profiles
being interchanged, without loss of a connecting pin (cf. Fig. 2-14).
To do this, proceede as follows:
1. Insert the coding profile
2. Insert the coding carrier
recesses.
A coding profile and a coding tab facing one another prevent the connector part
from being inserted.
The connector element can be easily plugged in when the coding profiles and tab
do not oppose each other.
