Removing from the S7-300 standard rail
To remove the device, you require a slotted screwdriver with a 5.5 mm wide blade.
Note
When uninstalling the IE
Switch X-400, hold it by the backplane and not by the modules,
evice may be damaged.
To remove the device, follow the steps below:
1. Remove the covers and the dummy cover.
2. If media modules are inserted, remove them as well.
First loosen the screw below the labeling strip of the module.
3. Using a slotted screwdriver with a 5.5 mm wide blade, loosen the two captive screws in
the backplane.
4. Pull out the lower part of the basic device slightly towards the front and lift it from the S7-
300 standard rail.
Installing / uninstalling with a 35 mm DIN rail
Installation on a 35 mm DIN rail
If the IE Switch X-400 is liable to be subjected to severe vibration (> 10 g), use the S7-300
standard rail for installation. The DIN rail does not provide adequate support for the
IE Switch X-400 with vibration greater than 10 g.
Since the two captive screws are not used to secure the device when installing on 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.
Note
When installing the IE
Switch X-400, hold it by the backplane and not by the modules,
otherwise the device may be damaged.
