Explosion-protected plugs and sockets, 7-pole
GHG 511 .7.. / 592 and 21-pole GHG 511 .9.. / 591
6.4 Closing the device
Before closing the wall sockets, check that
the cable entries are fitted correctly.
When placing the cover of the 7-pole wall
socket, pay attention that the switch handle
is in “0” position and the shaft of the switch
engages into the tappet hole on the switch
handle.
In order to ensure the required minimum
protection category, the cover screws must be
tightened down.
The screws on the plug and on the coupler
must be tightened down.
After connecting the cable, screw the
trumpet-shaped gland, Item 15, of the 21-pole
plug and coupler into the screw-in insert of the
plug or coupler sleeve by hand so that it seals. )
After this, tighten down the screws, item 16,
of the pull relief, Item 14. They shall be screwed
down tight enough to ensure sufficient pull
relief, to exclude any possible damage to the
cable and to safeguard it from twisting
(see p.18; fig.10).
Warning! Excessive tightening might impair
the pull relief.
After having connected the cable correctly
and checked the pull relief of the 7-pole plug,
screw down the pressure piece, Item 3, with
the screws, Item 4, tight enough to ensure
that it is sealed (see p.18; fig. 4).
Overtightening might impair the protection
category.
Any foreign matter shall be removed from
the device.
6.5 Putting into operation
Before putting the apparatus into operation,
the tests specified in the relevant national
regulations shall be carried out.
In addition to this, the correct functioning and
installation of the apparatus in accordance with
these operating instructions and other
applicable regulations shall be checked.
Check the plug for any damage before inserting
it into the socket.
The user shall ensure that an equipotential earth
is applied throughout when the plug and socket
is in operation.
The improper installation and operation of
the plugs and sockets may result in the
invalidation of the guarantee.
4. Remove the cover disc, item 19 fig.12,
on the contact pins or pins.
5. Remove pin or contact pin from conductor
(unsolder / cut off) and disengage the pin or
contact pin by taking off the interlocking
spring, item 20, using the dismantling tool,
item 12; fig.13 (COOPER CROUSE-HINDS
Order No. GHG 590 1903R0001). Pull the pin
out backwards.
6. To reassemble the plug / socket, proceed in
the reverse order or refer to Section 6.2 for

7. How to close the apparatus is described in
Section 6.4.
Apparatus modifications other than those
described or changes to apparatus are not
permitted.
9 Disposal / Recycling
When the apparatus is disposed of, the respec-
tive national regulations on waste disposal will
have to be observed.
In case of disposal you can obtain additional
information from your Cooper Crouse-Hinds
branch.
In order to facilitate the recycling of individual
components, plastic parts are provided with the

Subject to modifications or supplement of the
product range.
7 Maintenance / Servicing
The valid national regulations for the
servicing / maintenance of electrical
apparatus for use in potentially explosive
atmospheres shall be observed
(IEC/EN 60079-17).
Prior to opening the enclosure, it is
necessary to ensure that the voltage
supply has been isolated or to take suitable
protective measures.
The necessary intervals between servicing
depend upon the specific application and shall
be stipulated by the operator according to the
respective operating conditions.
During servicing, above all, the parts on which
the explosion protection depends,
(e.g. intactness of the flameproof components,
the enclosure, the seals and cable entries),
shall be checked.
If, in the course of servicing, it is ascertained,
that repairs are necessary, section 8 of these
operating instructions shall be observed.
8 Repairs / Modifications
Only original COOPER CROUSE-HINDS parts
shall be used for carrying out repairs.
In the event of damage to the flameproof
encapsulation, replacement of these
components is mandatory. In case of doubt,
the respective apparatus shall be sent to
Cooper Crouse-Hinds for repair.
Repairs that affect the explosion protection
may only be carried out by Cooper Crouse-
Hinds or by a qualified electrician in
compliance with the respective national
regulations (IEC/EN 60079-19).
If it is necessary to replace plug pins or socket
contact pins, proceed as follows
(see p.18; fig. 11, 12 and 13):
1. Open socket or plug as described in
section 6.2.
2. After opening, undo the slotted nut, Item 17,
of the plug or socket inserts using a suitable
tool (e.g. slotted nut spanner). To prevent
the through-screw from turning, hold screw
accordingly. (see p.18; fig.11)
3. Remove the front cover that bears the
designations of the plug or socket pins.
Warning:
The cover discs for the plug or socket pins
can fall out. To avoid this, hold the socket or
plug insert facing upwards.
