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).
