12 EMC fan/outlet filter
To achieve EMC protection, the EMC fans and EMC
outlet filters should be snapped into the mounting
cut-out and screw-fastened using the screws supplied.
Next, the four contact foils should be stuck on all-
round between the fan-and-filter unit and the inside of
the enclosure as shown in the following illustration.
