Use/Properties

The GHG 512 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 512 are fitted with a load switch
and can be used up to max. 32 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 400 V that corresponds to the voltage
range 380-415 V).
The apparatus connected to the plug shall be suitable for the applied
mains voltage.
Page 15, fig. 1
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.
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.
Page 15, fig. 2
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, 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 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).
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 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.
(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.

Page 15, fig. 2)
The wall sockets, flange sockets and couplers shall be mounted so
that the plug hole points downwards.
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
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.
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, fig. 4, item 2 is re moved from the pin bushing,
fig. 4, item 1, after the fastening screws fig. 3, item 3, have been
unscrewed. Thereafter, the plug insert can be connected to the connec-
tions of the plug pins (fig. 4, view 1,).
Page 12
Attention: When the fastening screws (fig. 3, item 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.
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 interna-
tional rules (e.g. use of sleeves for strands).
