Fitting Cable Glands
The ingress protection rating (IP6x) that is stated on the certification label
must be maintained.
Where the installer drills cable entries, they must be installed in accordance
to the areas/limitations as specified on the certified drawings and in
accordance with the enclosure certificate.
Where adjacent cable entries are installed, sufficient clearance must be
maintained to allow the fitting of sealing/retaining washers and the rotation
of the cable gland hexagons.
If site drilling takes place, carefully remove any drilling debris, particularly
debris that is close to sealing areas. Take care that the material does
not become overheated and that there is no visible deformation of the
enclosure. For the installation of cable glands it is necessary to follow the
guidelines as stated in the instructions issued by the manufacturer.
Earthing and Bonding
The Klippon STB enclosures are fitted with an internal / external M6 earth
®
stud as standard. Max. connection cross-section 25 mm². For larger cross-
sections, please contact Weidmüller.
It is important when providing protective wiring that the correct size of
conductor is used and that this is connected to a suitably sized earth stud.

applications.
