Cable Entries (Kle); Blanking Plug; Sockets; 6.3.2 Plug / Coupler; Closing The Device - Eaton CROUSE-HINDS Série Mode D'emploi

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.
Warning: Metal plates and metal glands shall be incorporated in the
potential equalization.

6.3.2 Plug / coupler

Page 15, fig. 4
In general, only the sealing inserts item 3 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
(see technical data).
Page 15, fig. 2
After having connected the cable, the coupling ring item 4 is to be
screwed fingertight until the sealing effect is obtained.
(see technical data).
Then the screws item 5, of the pull-relief item 6, are to be tightened down
(see technical data)..
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.
Page 16
This earth connection is inserted through a M6 drill in the inner wall of the
enclosure fig. 5.
Warning: Metal plates and metal glands shall be incorporated in the
potential equalization.

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
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 throug-
hout 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
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 discon-
nected 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
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
When the apparatus is disposed of, the respective national regulations on
waste disposal will have to be observed.
In case of disposal you can obtain additional information from your Cooper
Crouse-Hinds branch.
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.
