Safety instructions
a
The GHG 515 plugs and sockets are
not suitable for Zone 0 and Zone 20
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
apparatus, the permissible ambient
temperature, the rated terminal cross
section and the self-heating of the appara-
tus, that is mainly due to the power
dissipation, shall be taken into account (test
criterion for the self-heating is an overload of
10%).
The requirements of the IEC/EN 60079-31
regarding excessive dust deposits and
temperature to be considered from the user.
Before opening the apparatus, ensure that it
has been isolated from the voltage supply,
or take appropriate protective measures.
Modifications or changes to the plugs and
sockets are not permitted.
They shall be used for their intended
purpose and in a perfect and clean condi-
tion.
Only original COOPER CROUSE-HINDS parts
may be used as replacements and for
repairs.
Repairs that affect the explosion protection,
may only be carried out by COOPER
CROUSE-HINDS or a qualified electrician in
compliance with the respective national
regulations.
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
associated COOPER CROUSE-HINDS plugs
in an undamaged condition.
The plugs type GHG 515 .. shall only be used
in wall sockets of the series GHG 515 ... ,
GHG 519 ... and GHG 525 ... .
The plugs may also be used in any industrial
IEC socket outlets series I.
The socket insert and the actuating switch
are mechanically interlocked in such a way
that operation (switching on) is only
possible 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!

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 9001:2008 and
EN ISO/IEC 80079-34:2011.
The apparatus are conform to the standards
specified in the EC-Declaration of conformity,
enclosed separately.

Field of application
The plugs and sockets GHG 515 are suitable for
use in Zone 1 and 2 and 11 hazardous areas
acc. to IEC/EN 60079-10-1 and
IEC/EN 60079-10-2!
The enclosure materials employed, including
the exterior metal parts, are made of high-quali-
ty materials which ensure a corrosion protec-
tion and resistance to chemical substances
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 aggressive
atmosphere, please refer to manufacturer.
5 Use/Properties
The GHG 515 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 hazardous
areas. The plugs and sockets can also be used
in a „normal industrial area“.
The low-voltage plugs and sockets GHG 515 are
fitted with a load break switch and can be used
up to max. 125 A (see technical data).
The plugs and sockets can generally be used
for the voltage range laid down in IEC/EN 60309
(e.g. UN 400V that corresponds to the voltage
range 380 V - 415 V).
The apparatus connected to the plug shall
be suitable for the applied mains voltage.
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, Figs. 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. COOPER CROUSE-
HINDS.
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 1. 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.
