CAUTION
If the IE Switch X-400 with extender is liable to severe vibration (> 10 g), use the S7-300

the right of the basic device on the DIN rail to be able to align the guide bolts of the extender
with the holes in the basic device during installation.
Note
Protective caps and CV490 2x100 covers must be fitted to all slots without media modules.
