Field of application

The entries and components covered by
these instructions (see Technical Data) are
suited for mounting in potentially explosive
atmospheres in Zone 1, Zone 2 and Zone 21,
Zone 22 accordance with IEC 60079-10!
The materials used, including the exterior
metal parts, are high quality materials that
ensure a corrosion resistance and resistance
to chemical substances according to the
requirements for use in a "normal industrial
atmosphere":
- impact resistant polyamide
Through hole
- stainless steel AISI 316 L
In case of use in an extremely aggresive
atmosphere, please refer to manufacturer
5. Application / Properties
All the cable entries and components
covered by these operating and mounting
Counter-nut
instructions are suited for use in enclosures
and apparatus in the type of protection
"Increased Safety".
Consider table "Temperature table" on page
18 with installation.
Cable entries and enlargement glands are
used for feeding fixed cables into enclosures
and apparatus.
Warning: Cables shall be secured in such
a way (e.g. with a cable clamp) that they
cannot be pulled out of the entry.
Counter-nut
Trumpet-shaped cable glands are used for
feeding flexible cables into enclosures and
apparatus.
"uneven"
Warning: The fitting of seal inserts one
inside the other or the interchanging of
seal inserts of different entries to reduce
the cable opening is not permitted.
Reducing glands can be used to reduce the
size of threaded or through holes in
enclosures to a smaller thread size.
with seal
Warning: The screwing of several
reducing glands one inside the other to
reduce the threaded or through holes is
not permitted.
Blanking plugs are used to seal metric
COOPER CROUSE-HINDS cable entries and
COOPER CROUSE-HINDS multiple entries.
Screw glands are used to seal unused
through and threaded holes.
Any condensation in the apparatus can
escape via drain plugs (see 6.1, Mounting).
Applications other than those described
are not permissible without a written
declaration of consent from Messrs.
COOPER CROUSE-HINDS.
The instructions according to section 7 of
the operating instructions shall be
observed during operation.
The sole responsibility with respect to the
suitability and proper use of these entry
components with regard to the basic
conditions of these instructions (see
Technical Data) lies with the operator.
6. Installation
The relevant national regulations and the
generally recognized rules of engineering
apply for the installation and operation.
The improper installation and operation
of enclosures can result in the
invalidation of the guarantee.
Observe the special operational
conditions accordance to EN/IEC 60069-14.
6.1

Mounting

Warning: Prior to mounting, ensure that
the threads of the entry components
match the threads of the apparatus or
enclosure.
The mounting of entry components with
damaged or dirty threads can impair the
IP degree of protection.
6.1.1

Cable entries (KLE)

The intermediate gland (see Fig. 1) of the
cable entries shall be fitted with a suitable
tool, e.g. fork, ring or box spanner.
It is mounted directly in the threaded hole or via
the through hole of the enclosure (see Fig. 2).
If the sealing surfaces are uneven, seals shall
be used between the enclosure wall and the
intermediate gland (see Fig. 3). Counter-nuts
shall be used for walls with a thickness of
less than 4mm (see Fig. 2).
Cables are fed in as shown in Fig. 4.
The seal inserts shall be chosen to suit the
respective cable diameter (Figs. A,B,C and D).
The intermediate gland and the pressure
screw shall be tightened down to ensure the
specified minimum degree of protection.
Overtightening can impair the degree of
protection.
