3.3 Installation and removal procedures
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 cable
male end snap-on connection can gradually become loose.
Use a cable tie to fix the male end cable 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.
