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.
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" *
mounted on the plastic enclosure, it should be
connected with a max. 25mm² 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
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.
7
Maintenance/Servicing
The relevant national regulations which
apply to the maintenance/servicing of
electrical apparatus in explosive
atmospheres, shall be observed.
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.
is
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.
Modifications to the device or changes of
its design are not permitted.
9
Disposal/Recycling
When the apparatus is disposed of, the
respective 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.
