Installing / uninstalling with an S7-300 standard rail

Installing on an S7-300 standard rail
For installation, you require a slotted screwdriver with a 5.5 mm wide blade.
Note
When installing the IE Switch X-400, 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. Tilt the basic device slightly towards the back with the upper groove on the edge of the
S7-300 standard rail and push in towards the bottom. In this position, the basic device
should not slip off but it can be adjusted horizontally to the left or right until the required
position is achieved.
2. Remove the covers and the dummy cover.
3. If media modules are inserted, remove them as well.
First loosen the screw below the labeling strip of the module.
4. Using a screwdriver with a 5.5 mm wide blade, tighten the two captive screws in the
backplane until the basic device can no longer be moved to the side.
Note
Only horizontal installation permitted (ventilation slit top/bottom).
