Flexible cables shall be used with trumpet-
shaped cable glands or other suitable
entries with additional pull-relief.
When using cable entries with a lower IP
protection than that which applies to the
device (see page 3, technical data), the IP
protection of the whole device will be
reduced. The mounting directives applicable
to the cable entries used shall be observed.
Unused holes shall be closed with a certified
blanking plug in order to establish the
minimum protection category. In case of
sealing inserts that are cut out, it shall be
ensured that the insert is properly adapted to
the cable diameter.
Care has to be taken that, when fitting the
cable entries, sealing inserts appropriate to
the cable diameter are used.

Cooper Crouse-Hinds GmbH
Explosion protected plug and socket system 63A, GHG 518
In order to ensure the required minimum
3
protection category, the cable glands are to be
tightened down.
Overtightening might impair the protection
category.

All vacant metric CEAG cable entries shall be
closed with the certified blanking plug for
metric cable entries.
Attention: Metal flanges, metal plates and
metal cable glands shall be included in the
11
equipotential earth connection.
6.3.2
Plug
In general, only the sealing inserts, fig. 6,
item 12, fitted in the plug may be used.
When mounting the cable, attention has to be
paid that sealing inserts matching the cable
L3
diameter be used.
After having mounted the cable, the coupling
N
ring, fig. 6, item 4, is to be screwed fingertight
until the sealing effect is obtained. Then the
PE
screws, fig. 6, item 5, of the pull-relief, fig. 6,
item 6, are to be tightened down.
Mind! Overtightening might impair the pull-
relief effect!

In order to ensure the required minimum
11
protection category, the cover screws, the
screws of the plug shall be tightened down.
Overtightening might impair the protection
category. Any foreign matter shall be
removed from the device.

Taking into operation
Prior to taking the apparatus into operation,
the tests specified in the relevant national
regulations shall be carried out. Apart from
that, the correct functioning and installation of
the apparatus in accordance with these
operating instructions and other applicable
regulations will have to be checked.
Check the plug for any damages before
putting it in the socket.
The user must ensure that a uniform
equipotential earth applies throughout when
the plug and socket system is operated.
The inappropriate installation and
operation of the plugs and sockets can
entail the loss of warranty.
7
Maintenance/Servicing
The relevant national regulations which
apply to the maintenance/servicing of
electrical apparatus in explosive
atmospheres, shall be observed.
(IEC/EN 60079-17).
Before opening the enclosure, make sure
that the device is disconnected from the
voltage, or take appropriate protective
measures.
The required maintenance intervals depend on
the specific application and will therefore have
to be determined by the user dependent on
the conditions of use.
When servicing the plugs and sockets,
particularly those parts that are decisive for
their type of protection against explosion will
have to be checked (e. g. intactness of
flameproof enclosed components, of the
housing, firm fit of the cable entries and
efficacy of gaskets).
If during servicing, repairs prove to be
necessary, section 8 of these operating
instructions will have to be observed.

Repair/Overhaul/
Modifications
Repairs and overhaul may only be carried out
with genuine COOPER CROUSE-HINDS /
CEAG spare parts.
Should the flameproof enclosure be
damaged, only a replacement will be
permitted. In case of doubt, the respective
apparatus will have to be returned to
COOPER CROUSE-HINDS / CEAG for repair.
Repairs that affect the explosion
protection, may only be carried out by
COOPER CROUSE-HINDS / CEAG or a
qualified electrician in compliance with
the applicable national rules
(IEC/EN 60079-19).
Modifications to the device or changes of
its design are not permitted.
9
Disposal/Recycling
When the apparatus is disposed of, the
respective national regulations on waste
disposal will have to be observed. In order to
facilitate the recycling of individual
components, plastic parts are provided with
the identification mark of the plastic material
used.
