Special conditions:
ATEX - IEC
This symbol indicates that special conditions
apply for a safe operation in accordance with
the EC Type Examination Certificate /
IECEx Certificate of Conformity.
2.1 Safety instructions
The operations must be carried out by
electrical suitably trained in
hazardous area with knowledge of
increased safety explosion protec-
tion IEC/EN 60079-14.
All the entries and components listed in
these operating and mounting instructions
are not suited for use in Zone 0 and Zone 20.
In addition, they may not be used as direct
cable entries or seals for flameproof enclo-
sures in potentially explosive atmospheres in
Zone 1, Zone 2 and Zone 21, Zone 22.
They shall be used for their intended purpose
and shall be in a perfect and clean state.
Prior to mounting, check the entries and
components, as well as the screw-in threads
of the apparatus into which they are to be
mounted to ensure that they are in a perfect
state.
The requirements of the IEC/EN 60079-0 and
EN/IEC 60079-31 regarding excessive dust
deposits and temperature to be considered
from the user.
The national safety rules and regulations for
the prevention of accidents, as well as the
safety instructions included in these
operating instructions, that, like this text, are
set in italics, shall be observed!

Conformity with standards
They have been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001 and EN ISO/IEC 80079-34.
The apparatus are conform to the standards
specified in the EC-Declaration of conformity,
enclosed separately.
References to standards and directives in these
operating instructions always relate to the latest
version. Other additions (e.g. details relating to
the year) shall be observed.

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 accord-
ance with IEC/EN 60079-10-1 and
IEC/EC 60079-10-2!
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
- stainless steel
In case of use in an extremely aggresive
atmosphere, please refer to manufacturer

Application / Properties
All the cable entries and components covered by
these operating and mounting instructions are
suited for use in enclosures and apparatus in the
type of protection "Increased Safety" .
Trumpet-shaped cable glands are used for
feeding flexible cables into enclosures and
apparatus.
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.
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.
