Removing the media module extender from the S7-300 standard rail
You require the following tools:
● slotted screwdriver with a 2,8 mm wide blade
● slotted screwdriver with a 5.5 mm wide blade
Note
To remove the extender, remove the media modules from slots 13 and 14.
When removing a media module extender from an S7-300 standard rail, the basic device
remains in position. Follow the steps below:
1. To remove an extender module, use a slotted screwdriver with a 5.5 mm wide blade, to
open the captive screw between slots 13 and 14 in the lower part of the extender module.
2. Remove the cover from slot 11 of the basic device.
3. Use a slotted screwdriver with a 2.8 mm wide blade to loosen the two captive slug screws
on slot 11 of the basic device in the upper and lower recesses as far as they will go.
4. Push the extender module slowly to the right while keeping it straight until the two guide
bolts of the extender module are completely outside the holes in the basic device.
5. Pull out the lower part of the extender module slightly towards the front and lift it from the
S7-300 standard rail.
6. Replace the right side panel of the basic device so that the guide bolts fit into the two
holes in the basic device.
7. Using a slotted screwdriver with a 2.8 mm wide blade, tighten the two captive slug screws
on slot 11. The screws lock the two guide bolts, so do not use excessive force when
tightening them.
8. Fit a suitable cover on slot 11 of the basic device.
Note
The basic device must not be used permanently without the right side panel.
Installing the media module extender on the 35 mm DIN rail
If the IE Switch X-400 with extender is liable to severe vibration (> 10 g), use the S7-300
standard rail for installation. The DIN rail does not provide adequate support for the media
module extender with vibration greater than 10 g.
For installation, you require a slotted screwdriver with a 2.8 mm wide blade.
