6.1.2 Installing / Uninstalling with a 35 mm Standard Rail
Installation on a 35 mm Standard Rail
! Caution
If the SCALANCE X-400 is liable to severe vibration (> 10 g), use the S7-300 rail
for installation. The 35 mm standard rail does not provide adequate support for the
SCALANCE X-400 with vibration greater than 10 g.
Since the two captive screws in slot 7 and between slots 8 and 9 are not used to
secure the device when installing on a 35 mm standard rail, it is not absolutely nec-
essary to remove the covers and the blind cover, although this does make it easier
to handle the basic device.
Notice
When installing the SCALANCE X414-3E, hold it by the backplane and not by the
modules, otherwise the device may be damaged.
To install the device, follow the steps below:
1. Place the central groove containing two spring clips on the back of the basic
device on the upper edge of the standard rail with the device tilted slightly to-
wards the back. Make sure that the two spring clips are located behind the
edge and are visible from the rear of the installation frame.
2. Press the basic device down and push in the lower part until you hear it click
into place in the standard rail.
3. Adjust the basic device to the right or left until it is in the required position.
Note
Only horizontal installation permitted (ventilation slit top/bottom).
