3 Conformity with standards
They have 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 is conform to the standards
specified in the EC-Declaration of conformity,
enclosed separately.
4 Field of application
The plugs and sockets GHG 511 are suitable for
use in Zones 1 and 2 as well as in Zones 21 and
22 in accordance with 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
When used in extremely aggressive atmosphere,
you can request additional information on the
chemical resistance of plastics used in your
responsible Cooper Crouse-Hinds branch.
5 Use/Properties
The GHG 511 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 511 are fitted with a load
switch and can be used up to max. 16 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 380-415V).
The apparatus connected to the plug shall
be suitable for the applied mains voltage.
In order to switch on the socket, the plug is
inserted, pushed fully home and then turned
through approx. 45° to the right. Thereby the
plug is locked in the socket (see page 15, fig. 1).
For switching off and pulling the plug, proceed
in inverse order.
After separating the plug from the socket, the
latter shall be closed with the hinged cover and
secured with the bayonet ring. The plug can be
pushed into the socket and pulled out of it only
whilst the socket is switched off.
In order to ensure the socket’s type of
protection acc. to the type label also with the
plug being inserted, the bayonet ring of the plug
(see page 15, fig. 2, item 2) is turned to its stop
onto the socket.
The data as per point 3 and 4 will have to
be taken into account with the use.
Applications other than described are not
permitted without Cooper Crouse-Hinds’s
prior written consent.
For the operation, the instructions stated in
section 7 of the operating instructions will
have to be observed.
From time to time, the locking function
protecting against inappropriate use e. g. of
industrial plugs in zone 1 has to be checked.
In the open air, the plugs must be kept with the
plug opening (pin side) pointing downwards or
be closed with protective plug caps available
as an optional extra (see general catalogue).
The user alone is responsible for the
appropriate use of this plug and socket
system in consideration of the basic
conditions existing at the plant
(see technical data).
After a short in the circuit, the functioning of
the plug and socket system and of the plugs
has to be checked.
Since the switch contacts can no more be
checked because of the flameproof enclo-
sure, the complete switch insert (flange
socket) will have to be replaced after
repeated short circuits.
