Coding Connector Parts to Prevent Incorrect Usage

You can order a connector set with coding profiles and coding tabs as an
accessory for the C7-635 (see accessories in Section 2.2).
Caution
!
It is highly recommended that you code the connectors, as unintentionally using
the wrong connector may damage the device.
Coding the Connectors
The coding profiles ➀ and coding tabs ➁ (see Figure 3-18) enable you to code
connectors without loss of pole to prevent incorrect usage. Use the following
procedure:
1. Insert coding profile ➀ on connector part ❶ into the slots provided.
2. Insert coding carrier ➁ on the main housing ❷ into the corresponding recesses.
A coding profile and a coding tab facing one another prevent the connector part
from being inserted.
If a coding profile and coding carrier do not face one another, the connector part
can be inserted without difficulty.
