Proceed as follows to connect and establish
contact with the plug and socket system (see
also Fig 3, A-F):
1.
Insert the plug or inlet with the key in
the correct position in the respective keyway
of the coupler/flange socket until Stop 1 is
reached ( A+B)
Ensure that the components being joined
together have the same coding (time.)
2.
Then turn the plug or coupler through
ca. 30° to the right until reaching the stop and
then insert fully (C+D).
3.
Finally, screw down the coupling ring
tightly to establish the IP protection and the
mechanical connection (E+F).
Proceed in the reverse order to disconnect
the plug and socket system.
The components of the plug and socket
system are generally to be kept sealed.
When opened, the live plug and socket
system components shall be sealed
immediately after disconnection using the
protective cap.
The data according to sections 3 and 4
shall be taken into account during use.
Applications other than those described
are not permissible without a written
declaration of consent from the
manufacturer. 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 the plug and
socket systems with regard to the basic
requirements of these instructions (see
Technical Data) lies with the operator.
After a short circuit, the plug and socket
systems shall be checked to ensure that
they function correctly. As, after several
short circuits, the flameproof
encapsulation of the plug pins and
contacts sockets is no longer guaranteed,
the complete plug and socket system
(flange socket/plug or coupler/plug or
inlet/coupler) shall be replaced.

The explosion protection is no longer
guaranteed if the plug and socket system
components are not plugged together
correctly.

Installation
The relevant national regulations and the
generally recognized rules of engineering
apply for the installation and operation
(IEC/EN 60079-14).
For information on connection cables see
Data Sheet GHG 902 5012 F0001 on our
internet website: www.ceag.de.
6.1
Mounting
Preferably flange sockets and inlets shall be
mounted with the plug opening facing
downwards.
Flange sockets, inlets and angle pieces
may only be installed in protective
apparatus or enclosures that have been
certified for the respective application.
When mounting flange sockets, inlets or angle
pieces in a flameproof enclosure, in
accordance with IEC/EN 60079-1, Table 3,
the volume of the enclosure or of the
apparatus is limited to max. 2 dm³.
The threaded boreholes in the flameproof
enclosure or built-in apparatus shall fulfil
the minimum requirements according to
IEC/EN 60079-1.
The plug and sockets system components,
flange socket, inlet or angle piece, as well as
the respective boreholes and screw-in
threads of the enclosures or apparatus shall
be checked prior to mounting to ensure that
they are not damaged and in a clean state.
Before screwing-in components, ensure that
the threads of the screw-in components
(flange socket, inlet or angle piece)
corresponds to that of the threaded borehole
in the enclosure or apparatus.
When mounting screw-in components, it
is necessary to ensure that the sealing
ring is in the correct position and that it is
not damaged. Components made of metal
only may be used in flameproof
enclosures.
The screw-in components shall be
screwed in tightly into the enclosure (see
Technical Data for test torque).
To adapt the position of the screwed-in angle
piece in relation to the entry piece, undo the
screws, Items 3 and 5, turn the angle piece,
Item 2, until it is in the desired position and
screw the screws, Item 3, back into the
respective visible threaded holes. Then, by
means of the anti-torsion screw, Item 5, the
angle piece is safeguarded against twisting
(see Fig. 1, page 4).
Suitable measures shall be applied (e.g.
adhesive, locking and retaining with anti-
torsion screw, Item 5, see also Fig. 2, page 4)
to safeguard screwed-in flange sockets,
inlets or angle pieces against twisting or self-
loosening.
The explosion protection is no longer
guaranteed if mounted incorrectly or if
mounted in a damaged/dirty screw-in
thread.
For an easy identification of the different
versions oloured rubber rings are included.
The rubber rings shall be slipped onto the
housing. (Fig, 3b)(see Page 2)
