4. Seal all openings not required for cables with sealing plugs (position D in the figure
above).
5. Fit these sealing plugs in a strain relief clamp. The lower surrounding notch must be
enclosed by the toothing of the strain relief clamp (as shown in the figure below). Press
the strain relief clamp into the housing until the sealing plug is located completely in the
opening of the housing seal.

Note
Keep unused sealing plugs and strain relief clamps for later use.
The oval FO cable specified for use with the SCALANCE W786 does not have a circular
cross section. As a result, remember the following points when connecting up such cables.
Fit the supplied adhesive sealing foil at the point where the cable goes through the housing
seal. Only then will you achieve perfect sealing of the housing. Follow the steps outlined
below:
1. Remove the protective foil and wind the adhesive sealing foil completely around the oval
FO cable at the appropriate position transverse to the cable.
When you fit the strain relief clamp, make sure that the FO cable is in the correct position.
The shorter sides of the cable must make contact with the toothing of the strain relief clamp.
