Removing from the 35 mm Standard Rail
Since the two captive screws in slot 7 and between slots 8 and 9 are not used to
secure the device, when removing it from a 35 mm standard 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 removing the SCALANCE X414-3E, 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. Push the basic device down until the lower part can be pulled away from the
standard rail to the front.
2. Lift the SCALANCE X414-3E up and off the standard rail.
