2.1 Safety instructions
Target group:
For skilled electricians and suitable qualified, instructed
personnel in accordance with national legislation, including
the relevant standards and, where applicable, in acc. with
IEC/EN 60079-14 on electrical apparatus for explosive atmospheres.
They are not suitable for Zone 0 and Zone 20 hazardous areas. The
temperature class and explosion group marked on the apparatus
shall be observed.
Modifications to the plugs and sockets or changes of their design are
not permitted. They shall be used for their intended purpose and in
perfect and clean condition.
The requirements of the IEC/EN 60079-31 regarding excessive dust
deposits and temperature to be considered from the user.
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 apparatus
that is mainly due to the power dissipation shall be taken into
account (test criterion for the self heating is an overload of 10%).
Prior to taking the plugs and sockets into operation, they will have
to be checked in accordance with the instruction as per section 6.
The sockets may only be used with the associated Cooper Crouse-
Hinds plugs in undamaged condition.
The interlocking switch of the socket is mechanically secured and
cannot be connected without plug.
The plugs GHG 543/531 can further on be inserted with the sockets
of the series GHG 543/GHG531.
Flange sockets may only be used in protective enclosure or apparatus
that have been certified for the respective application.
Observe the national safety rules and regulations for prevention of
accidents as
well as the safety instructions included in these operating instruc-
tions and set in italics the same as this text!
3 Conformity with standards
The apparatus is conform to the standards specified in the EU-Declaration
of conformity, enclosed separately.
References to standards and directives in these operating instructions
always relate to the latest version. Other additions (e.g. details relating to
the year) shall be observed.
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- quality materials which ensure a corrosion protection 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 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 18, 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 18, 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 operat-
ing instructions will have to be observed.
From time to time, the locking function protecting against inappro-
priate 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).
