SCALANCE X-400 BA
90 Operating Instructions, 03/2009, C79000-G8976-C186-07
1. Remove the cover from slot 11 of the basic device.
2. Remove the right-hand side panel of the basic device. To do this, use a slotted
screwdriver with a 2.8 mm wide blade to loosen the two captive slug screws on slot 11 in
the upper and lower recesses as far as they will go.
3. Remove the side panel of the basic device from the basic device to the right.
Note
Keep the panel in a safe place in case the extender needs to be removed again later.
4. Place the central groove containing a spring clip on the back of the extender module on
the upper edge of the DIN rail with the module tilted slightly towards the back. Make sure
that there is adequate clearance between the guide bolts of the extender module and the
basic device.
5. The spring clip must be located behind the edge of the DIN rail so that it is visible from
the rear of the frame.
6. Press the extender module down and push in the lower part until you hear it click into
place in the DIN rail.
7. Push the extender module slowly to the left while keeping it straight and without skewing
and check that the two guide bolts on the extender fit into the holes in the basic device.
Then push the extender module to the left as far as it will go so that it is flush with the
right side of the basic device.
8. 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.
9. Fit the CV490 4x100 cover on slot 11 of the basic device. Make sure that the media
module terminal strips of slots not occupied by media modules have protective caps fitted
and that the CV490 2x100 covers are in place.
