Conformity with standards

The plugs meet the requirements of EN 50014,
EN 500018 and EN 500019 (IEC 79-0, IEC 79-1,
IEC 79-7).
They have been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001.
94/9 EC: Equipment and protective systems
intended for use in potentially explosive
atmospheres.
The plugs also fulfil further requirements such as
those of the directive on electromagnetic
compatibility (89/336/EEC).

Field of application

The plugs and sockets GHG 534 are suitable for
use in Zones 1 and 2 in accordance with
EN 50145.
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
In case of use in an extremely aggressive
atmosphere, you can obtain information
concerning the chemical resistance of the
materials used from your Cooper Crouse-Hinds
branch.
5 Use/Properties
The GHG 534 plugs 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 534 are fitted with a load
switch and can be used up to max. 63 A (see
technical data). The plugs 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.
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 interlocking switch can be
swithced on! After switching on the socket pulling
the plug is no longer possible.
For switching off and pulling the plug, proceed in
inverse order.
Explosion protected plug 63 A, GHG 534
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.
The user alone is responsible for the
appropriate use of this plugs 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 of the sockets can
no more be checked because of the
flameproof enclosure, the complete switch
insert (flange socket) will have to be replaced
after repeated short circuits.

Installation

For the mounting and operation, the respective
national regulations as well as the general rules of
engineering will have to be observed.
The improper installation and operation of plugs
may result in the invalidation of the guarantee.
6.1 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.
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.
The supply terminals are designed for the
connection of copper conductors. If multi- or
fine-wire connecting cables are used, the wire
ends will have to be handled in acc. with the
applicable national and international rules
(e.g. use of sleeves for strands).
6.2 Cable entries (KLE);
blanking plugs
In general, only the sealing inserts fitted in the
plug may be used. When mounting the cable,
attention has to be paid that sealing inserts
matching the cable diameter be used.
Mind! Overtightening might impair the
pull- relief effect!

6.3 Closing the device

In order to ensure the required minimum
protection category, the screws of the plug shall
be tightened down.
Overtightening might impair the protection
category.
Any foreign matter shall be removed from the
device.

6.4 Taking into operation

Prior to taking the apparatus into operation, the
tests specified in the relevant national regulations
shall be carried out. Apart from that, the correct
functioning and installation of the apparatus in
accordance with these operating instructions and
other applicable regulations will have to be
checked.
Check the plug for any damages before
putting it in the socket.
The user must ensure that a uniform equipotential
earth applies throughout when the plug and
socket system is operated.
The inappropriate installation and operation
of the plugs and sockets can entail the loss of
warranty.
