Fitting Cable Glands

The ingress protection rating (IP6x) that is stated on the certification label
must be maintained.
The enclosure may be supplied complete with cable entries. If additional
cable entries must be drilled out, then be sure to comply with the specified
zones shown in the drawings.
Where adjacent cable entries are installed, sufficient clearance must be
maintained to allow for 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
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.
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.
The following table details the size of cable that is required for a variety of
applications.
