Plug/Coupler; Closing The Device; Taking Into Operation; Maintenance/Servicing - Eaton CROUSE-HINDS Série Mode D'emploi

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

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 18, 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 19, 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 through-
out when the plug and socket system is operated.
The inappropriate installation and operation of the plugs and sockets
can entail the loss of warranty.

The relevant national regulations which apply to the maintenance/
servicing of electrical apparatus in explosive atmospheres, 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, parti cularly 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.
7.1
The 4 fixing screws of the flange socket have to be considered in the
maintenance intervals too.
The test torque have to be checked
(see Technical data).

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.
