Removing the SCALANCE X408-2 from a 35 mm DIN rail
Since the two captive screws are not used to secure the device when removing from a 35
mm DIN rail, it is not absolutely necessary to remove the covers and the blind cover,
although this does make it easier to handle the basic device.
NOTICE
When uninstalling the SCALANCE X408-2, hold it by the backplane and not by the
modules, otherwise the device may be damaged.
To remove the device, follow the steps below:
1. Using a slotted screwdriver with a 5.5 mm wide blade, pull down the clip on the basic
device slightly and pull out the lower part of the basic device to the front so that the spring
clips can no longer engage.
2. Lift the IE Switch X-400 up and off the DIN rail.
