7.3
Terminal Coding
It is possible to code the Push-In terminals with coding pins, which are in the
scope of delivery. The coding prevents polarity reversal.
7.3.1
Coding of X1
7.3.2
Coding of X2, X7, X8, X9
There are certain specifications for coding the plug-in terminals and
terminal blocks.
The coding of plug-in terminals and terminal blocks prevents
similar connectors from being inserted accidentally. Special coding strips and
coding profiles ensure that only coded counterparts can be connected. The
following is an overview of the relevant application.
Insert the coding element (
A
) at the
desired positions on the push-in
terminal.
Insert the coding element (
B
) at the
corresponding positions on the terminal
block.

The push-in terminal as well as the appropriate terminal block must be
coded, so that it is not possible to interchange them!
If, for example, only
the plug-in terminal is coded, it can be plugged into any terminal block.
To encode the push-in terminals, the
respective coding nose can be
removed using pliers.
