Eaton GHG 511 Betriebsanleitung Seite 7

3 Conformity with standards
They have 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.
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
In case of use in an extremely aggresive
atmosphere, please refer to manufacturer.
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 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 12, 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 activate the socket, the plug is
pushed fully home. Then the switching ring on
the plug can be turned through 45° to the right
in order to unlock the interlocking switch
(see page 12, fig.1)!
Explosion protected plug and socket system 16A, GHG 511
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 12, 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.
6 Installation
For the mounting and operation, the respective
national regulations as well as the general rules
of engineering will have to be observed
(IEC/EN 60079-14).
The improper installation and operation of plugs
and sockets may result in the invalidation of the
guarantee.
6.1 Mounting
The wall sockets can be mounted without
opening their 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 dimensional
drawing) and it must not damage the hole (e. g.
use of a washer). The device shall be fastened
diagonally with at least 2 screws.
The wall sockets, flange sockets and
couplers shall be mounted so that the plug
hole points downwards (see page 12, fig. 2).
The wall sockets can be clipped onto the
Cooper Crouse-Hinds mounting plate size 4.

They are laterally pushed into the guiding
groove on the left-hand side of the mounting
plate.
The respective mounting instructions will
have to be observed.

6.2 Opening the device/
Electrical connection
Before opening the apparatus, ensure that it
has been isolated from the voltage supply,
or take appropriate protective measures.
The electrical connection of the device may
only be carried out by skilled staff
(IEC/EN 60079-14).
The conductors shall be connected with
special care in order to maintain the
explosion category.
The insulation of the conductors shall reach
up to the terminal. The conductor itself shall
not be damaged.
The connectible min. and max. conductor
cross-sections shall be observed (see
technical data).
Taking into account the respective regulations,
the properly bared conductors of the cables
shall be connected.
The plug insert (page 12, item 2, fig. 4) is
removed from the pin bushing (page 12, item 1,
fig. 4), after the fastening screws (item 3, fig. 3)
have been unscrewed. Thereafter, the plug
insert can be connected to the connections of
the plug pins (see page 12, view 1, fig. 4).
Attention: When the fastening screws (page
12, item 3, fig. 3) get lost, they will have to
be replaced by similar screws or to be
ordered directly from the manufacturer.
Assembly is made in inverse order, after the
cable has been connected.
All screws and/or nuts of the supply terminals,
also of those remaining vacant, shall be
tightened down.
Excessive tightening may affect or damage
the connection.
