Table 3- 10 Installing and removing the female connector of the expansion cable
Task
Note
Installing the expansion cable in a vibration environment
If the expansion cable is connected to modules that move or are not firmly fixed, the
connection on the cable ends can gradually become loose.
Use a cable tie to fix the cable ends on the DIN-rail (or other place) to provide extra strain
relief.
Avoid using excessive force when you pull the cable during installation. Ensure the cable-
module connection is in the correct position once installation is complete.
