2 Safety instructions
The operations must be carried
a
out by electrical suitably trained in
hazardous area with knowledge of
increased safty explosion protection
IEC/EN 60079-14.
The GHG 519 plugs and sockets are not
suitable for Zone 0 and Zone 1 hazardous
areas.
The temperature class and explosion group
marked on the apparatus shall be observed.
To ensure adherence to the temperature
class stated on the type label of the ap-
paratus, the permissible ambient tempera-
ture, the rated terminal cross section and the
self-heating of the apparatus, that is mainly
due to the power dissipation, shall be taken
into account (test criterion for the self-heat-
ing is an overload of 10%).
Before opening the apparatus, ensure
that it has been isolated from the volt-
age supply, or take appropriate protective
measures.
Modifications or changes to the plugs and
sockets are not permitted.
They shall be used for their intended pur-
pose and in a perfect and clean condition.
Only original COOPER CROUSE-HINDS /
CEAG parts may be used as replacements
and for repairs.
Repairs that affect the explosion protec-
tion, may only be carried out by COOPER
CROUSE-HINDS / CEAG or a qualified elec-
trician in compliance with the respective
national regulations (IEC/EN 60079-17).
Prior to being put into operation, the plug
and socket shall be checked in accordance
with the instructions in section 6.
The sockets may only be used with the as-
sociated COOPER CROUSE-HINDS / CEAG
plugs in an undamaged condition.
The plugs type GHG 519 .. shall only be
used in wall sockets of the series GHG 519
... and GHG 525 ... .
The plugs may also be used in any indus-
trial IEC socket outlets.
The socket insert and the actuating switch
are mechanically interlocked in such a way
that operation (switching on) is only pos-
sible when the plug is inserted.
Before initial operation, any foreign matter
shall be removed from the the plugs and
sockets.
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!

Explosion-protected plugs and sockets 125 A, GHG 519
3 Conformity with standards
The plugs and sockets has been designed,
manufactured and tested according to the state
of the art and to DIN EN ISO 9001:2015 and
EN ISO/IEC 80079-34:2011.
The apparatus are conform to the standards
specified in the EC-Declaration of conformity,
enclosed separately.)
4 Field of application
The plugs and sockets GHG 519 are suitable
for use in 2 hazardous areas acc. to
IEC/EN 60079-10-1!
The enclosure materials employed, including
the exterior metal parts, are made of high-
quality materials which ensure a corrosion
protection and resistance to chemical sub-
stances corresponding to the requirements in
a "normal industrial atmosphere":
- impact resistant polyamide
- glass-fibre reinforced polyester
- special steel AISI 316 L
In case of use in an extremely aggresive
atmosphere, please refer to manufacturer.
5 Use/Properties
The GHG 519 plugs and sockets are used for
the power supply of local controls with varying
locations, as well as of electrical installations,
mobile machinery and driving gear in hazard-
ous areas. The plugs and sockets can also be
used in a „normal industrial area" .
The low-voltage plugs and sockets GHG 519
are fitted with a load break switch and can be
used up to max. 125A (see technical data).
The plugs and sockets can generally be used
for the voltage range laid down in IEC 60309
(e.g. U 400V that corresponds to the
N
voltage range 380-415V).
The plug can only be inserted or withdrawn
when no voltage is applied.
The socket can only be switched on if the plug
is fully inserted.
In order to guarantee the type of protection
stated on the type label, also when the plug
has been inserted, the bayonet ring of the
plug, page 9, Fig. 2. item 2, has to be turned
until it reaches the stop on the socket.
To switch off and withdraw the plug, proceed
in the reverse order.
After withdrawing the plug from the socket,
seal the socket with the hinged cover and
secure it with the bayonet ring, page 9, fig. 1
and 2, item 9.
The data according to sections 3 and 4 shall
be taken into account during use. Applica-
tions other than those described are not
permissible without a written declaration of
consent from Messrs. CEAG.
During operation the instructions given in
section 7 of the operating instructions shall
be observed.
From time to time it is necessary to check
the functioning of the interlock that acts as
a protection against incorrect use, e.g. of
industrial plugs in Zone 2. See section 7,
Maintenance / Servicing.
When used in open air installations, the
plugs must be kept with the plug opening
(pin end) facing downwards or be sealed
with protective plug caps that are available
as an optional extra (see main catalogue).
The sole responsibility with respect to the
suitability and proper use of the plugs and
sockets with regard to the basic require-
ments of these instructions (see technical
data) lies with the operator.
After a short in the circuit, the functioning
of the plug and socket shall be checked.
As, due to the flameproof encapsulation, it
is not possible to check the switch contacts,
the complete switch insert has to be
replaced after repeated short circuits.
6 Installation
The relevant national regulations and the gen-
erally recognized rules of engineering apply for
the installation and operation
(IEC/EN60079-14).
6.1 Mounting
The wall sockets can be mounted without
opening the enclosure.
In case the wall sockets are mounted directly
onto the wall, they may rest evenly only at the
respective fastening points. The chosen screw
shall match the fastening hole (see dimen-
sional drawing) and it must not damage the
hole (e. g. use of a washer). The device shall
be fastened diagonally with at least 4 screws.
