Eaton CROUSE-HINDS CEAG GHG 512 Betriebsanleitung Seite 8

The plug insert (page 12, item 2, fig. 4) is
re moved 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.
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).
6.3 Cable entries (KLE);
blanking plugs
6.3.1 Socket
Generally, only certified cable entries and
blanking plugs are permitted for use. Flexible
cables shall be used with trumpet-shaped cable
glands or other suitable entries with additional
pull-relief.
When using cable entries with a lower
IP protection than that which applies to the
device (see technical data), the IP protection
of the whole device will be reduced.
The mounting directives applicable to the cable
entries used shall be observed.
Unused holes shall be closed with a certified
blanking plug in order to establish the minimum
protection category. In case of sealing inserts
that are cut out, it shall be ensured that the
insert is properly adapted to the cable diameter.
Care has to be taken that when fitting the cable
entries, sealing inserts appropriate to the cable
diameter are used.
In order to ensure the required minimum
protection category, the cable glands are to be
tightened down.
Overtightening might impair the protection
category.
All vacant metric COOPER CROUSE-HINDS
cable entries shall be closed with the certified
blanking plug for metric cable entries.

6.3.2 Plug/coupler
In general, only the sealing inserts fitted in the
plug or in the coupler may be used. When
mounting the cable, attention has to be paid
that sealing inserts matching the cable
diameter be used. After having connected the
cable, the coupling ring (page 12, fig. 2, item 4)
is to be screwed fingertight until the sealing
effect is obtained. Then the screws item 5, of
the pull-relief item 6, are to be tightened down.
Mind! Overtightening might impair the
pull-relief effect!
In case an "external earth connection" is
mounted on the plastic enclosure, it should be
connected with a max. 25 mm² wire.
This earth connection is inserted through a M6
drill in the inner wall of the enclosure (see
page 13, fig. 5).
Warning: Metal plates and metal glands
shall be incorporated in the potential
equalization.
6.4 Closing the device
In order to ensure the required minimum
protection category, the cover screws, the
screws of the plug and of the coupler shall be
tightened down.
The screws of the plug and the coupler shall be
tightened down.
Overtightening might impair the protection
category.
Any foreign matter shall be removed from
the device.
6.5 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 equipoten-
tial 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.

7 Maintenance/Servicing
The relevant national regulations which apply
to the maintenance/servicing of electrical
apparatus in explosive atmo spheres, shall be
observed (IEC/EN 60079-17).
Before opening the enclosure, make sure
that the device is disconnected from the
voltage, or take appropriate protective
measures.
The required maintenance intervals depend on
the specific application and will therefore have
to be determined by the user dependent on the
conditions of use.
When servicing the plugs and sockets,
particularly those parts that are decisive for
their type of protection against explosion will
have to be checked (e. g. intactness of
flameproof enclosed components, of the
housing, firm fit of the cable entries and
efficacy of gaskets).
If during servicing, repairs prove to be
necessary, section 8 of these operating
instructions will have to be observed.
8 Repair/Overhaul/
Modifications
Repairs and overhaul may only be carried out
with genuine COOPER CROUSE-HINDS spare
parts.
Should the flameproof enclosure be
damaged, only a replacement will be
permitted.
In case of doubt, the respective apparatus
will have to be returned to COOPER
CROUSE-HINDS for repair.
Repairs that affect the explosion protection,
may only be carried out by COOPER
CROUSE-HINDS or a qualified electrician in
compliance with the applicable national
rules (IEC/EN 60079-19).
Modifications to the device or changes of its
design are not permitted.
9 Disposal/Recycling
When the apparatus is disposed of, the respec-
tive national regulations on waste disposal will
have to be observed.
In order to facilitate the recycling of individual
components, plastic parts are provided with the
identification mark of the plastic material used.
Subject to modifications or supplement of the
product range.
