Installing and Removing the
Interface Submodules

Installation

5 - 66
To use an interface submodule, you must first install it in the CPU
(outside the central controller).
Caution
Switch off the power supply of the programmable controller
before removing the CPU.
Install your interface submodule in the following steps:
Step Action
1 Check the jumper settings of your interface submodule:
PG submod.
V.24 submod.
TTY submod.
RS422 A/485 submod.
SINEC L1 submod.
When the interface submodule is delivered, the jumpers
are already set so that you can usually fit it immediately.
2 Switch off the power supply of your PLC.
3 Remove the CPU.
4 Slacken both screws with which the cover of the
submodule receptacle is secured on the CPU, and remove
the cover.
5 Insert the interface submodule through the front plate into
the plug-in connector (components in the same direction
as the CPU).
6 Secure the submodule with the two screws with which the
cover was secured.
7 Insert the CPU in the central controller.
8 Switch the power supply of your PLC on again.
