6.2.4 Direct connection using
individual wires
The insulation shall reach up to the
terminal. The conductor itself shall not be
damaged.
The correctly stripped connection leads shall
be connected according to the relevant
regulations.
With multi-wire or fine-wire connection
leads, the ends of the wires shall be
treated in accordance with the valid
national or international regulations (e.g.
the use of wire-end ferrules).
The maximum current load of the
connected leads shall be taken into
account (see Technical Data).
To maintain the type of protection, the
cables shall be connected with special
care,
Flange sockets and inlets may only be
used in protective enclosures and
apparatus that have been approved for
the respective application. They shall be
screwed tightly into the enclosure or
angle piece (see Technical Data for test
torques).
Mounting see fig. 8
A
Together with the anti-torsion
protection, Item 2, screw the flange socket or
inlet, Item 1, tightly into the enclosure (see
Technical Data for test torque).
B
Safeguard the flange socket or flange
socket against twisting with the locking screw,
Item 3.
Warning!
When screwing in the flange sockets or
inlets, attention shall be paid to
connected cables or wires to prevent any
damage to the insulation.
In order to guarantee the explosion
protection, only inlets and flange sockets
made of metal may be fitted in the
boreholes of flameproof enclosures.
Suitable measures shall be applied (e.g.
adhesive, locking and retaining with anti-
torsion screw, Items 2 + 3) (available from
manufacturer if required, see also Fig. A) 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 and if the components of the plug
and socket system are not connected
correctly.

Cable entries

Ensure that the diameter of the cable entries
used matches that of the seal of the plugs
and couplers.
Section 6.2 shall be taken into account for
cable entries.
Generally only the seal inserts fitted in the
plug or coupler may be used.
6.4

Closing apparatus

After connecting the cables, tighten the
pressure screw, Item 2, (as shown in Fig. 9
and 10, page 28) of the plug or coupler (with
manual strength) until the strain-relief and seal
take effect (see Technical Data for test
torque).
The minimum degree of protection and
the explosion protection are only
guaranteed if the pressure screw is
tightened correctly.
Warning! Overtightening the pressure
screw can have a negative effect on the
strain relief / seal and damage the cable.
If required, the plug and socket system is
available with a padlocking facility for
safeguarding it when connected (shackle
diameter 4-6 mm), see also Fig. 11, page 28.

Putting into operation

Putting into operation Putting into operation Putting into operation Putting into operation
Before putting the apparatus into operation,
the tests specified in the individual national
regulations shall be performed.
In addition to this, before being put into
operation, the correct functioning of the
apparatus and installation of the components
in accordance with these operating
instructions and other applicable regulations
shall be checked.
Every time the plug is inserted into the flange
socket / coupler inspect it for damages.
The operator shall ensure that a common
earth potential is applied throughout during
operation of the plug and socket system.
The improper installation and operation
of the plug and socket systems may
result in the invalidation of the guarantee.
