5.11 Cable and conductor entries
Temperature controllers and safety temperature
limiters may only be fitted with cable and conduc-
tor entries or blind plugs for which an EC-type
examination certificate (Categories 2 G and 2 D)
has been issued by a European Notified Body as
per EN IEC 60079-0, EN IEC 60079-7 and EN
IEC 60079-31.
Cable and conductor entries may only be fitted
in the specially prepared holes that are blanked
off with blind plugs.
The cable and conductor entries must be
installed so as to prevent self-loosening and
ensure permanent sealing of the cable and con-
ductor entry points.
The spacing between the cable glands is such
that a torque wrench can be used to secure the
gland bodies of the cable and conductor entries
in the enclosure wall and to tighten the seals
around the cables.
In the factory the cable and conductor entries are
fitted with CEAG type GHG 960 923 P... cable
glands. The dimensions, the clamping ranges for
cables and wires and the torques are shown in
the tables in Annex A.
If other cable and conductor entries are installed,
the torques required and the corresponding
cable diameters will be found in the manual of
the manufacturer concerned.
If any cable and conductor entries are not used
or are no longer needed, the tapped holes and
redundant gland bodies must be blanked off with
suitable blind plugs or caps.
