Replacing A Front Connector - Siemens SIMATIC S7-1500 System Manual

Replacing a front connector

Introduction
When the front connector is first inserted into the I/O module, a part of the coding element
clips onto the front connector. When you replace a defective front connector with a new front
connector, then you must transfer the coding element into the new front connector.
Procedure
You have already removed the front connector from the module and loosened the wiring. If
you are using the front connector for an analog module, you also need to remove the power
supply element and shield element. Proceed as follows to replace the front connector:
1. Carefully remove the coding element from the front connector. Take care not to damage
the coding element.

2. Insert the removed coding element into the new front connector.

3. Insert the new front connector into the existing I/O module, until your hear it click into
place.
4. Wire the new front connector.
