Cable Entries (Kle); Blanking Plugs; Closing The Device/ Cover Closure; Taking Into Operation; Maintenance/Servicing - Eaton CROUSE-HINDS Série Mode D'emploi

In the case of building up the electrical
equipment in the „protective insulation"
version, appropriate sticker
( ) GHG 905 1002 P0005 can be requested by
the manufacturer.
If the inserted terminal rail is not equipped
completely with line-up terminals, the terminal
rail must be included in the equipotential earth
connection also.
6.3 Cable entries (KLE);
blanking plugs
Generally, only certified cable entries and
blanking plugs may be used.
Flexible cables are to be used with trum-
pet-shaped cable glands or other suitable
entries with additional pull-relief.
Intrinsically safe circuits (Ex-i) are to be
connected through the coloured (light blue)
cable entries.
The mounting directives applicable to the
cable entries used shall be observed.
When using cable entries with a lower IP
protection than that which applies to the
device (see technical data, page 6), the IP
protection of the whole device will be
reduced.
When using apparatus or cable entries for the
connection to or into the apparatus, when
applicable, the relevant special conditions for
safe use given in the individual certificates shall
be considered.
In order to establish the minimum protection
category, unused holes have to be closed with
a certified blanking plug.
Care has to be taken that when fitting the cable
entries, sealing inserts appropriate to the cable
diameter are used.
In case of sealing inserts that are cut out, it will
have to be ensured that the insert is properly
adapted to the cable diameter.
All vacant metric CEAG / CCH cable entries are
to be closed with the certified blanking plug for
metric cable entries.
In order to ensure the required minimum
protection category, the cable glands shall be
tightened down.
Overtightening might impair the protection
category.
Attention: When tightening the cap nut of
the type ADE 1F metal cable entry, the
screwing is to be protected against twisting
by means of a suitable tool.

6.4 Closing the device/
cover closure
Any foreign matter shall be removed from
the apparatus.
In order to ensure the required minimum
protection category, the cover screws are to be
tightened down.
Overtightening might impair the protection
category.

6.5 Taking into operation

Prior to taking the apparatus into operation, the
tests specified in the relevant national
regulations will have to 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.
Incorrect installation and use of the junction
boxes can invalidate the guarantee.

Maintenance/Servicing

The required maintenance intervals are set
according to their application and should
therefore be determined depending on the
conditions of use.
Before opening the enclosure make sure
that the apparatus is disconnected from the
voltage, or take the appropriate protective
measures.
In case of intrinsically safe circuits, working is
permitted while voltage applies.
The relevant national regulations which apply to
the maintenance/servicing of electrical
apparatus in explosive atmospheres, shall be
observed (IEC/EN 60079-17).
When servicing the apparatus, particularly
those parts that are decisive for the type of
protection against explosion, will have to be
checked (e. g. intactness of enclosure, cable
glands, efficacy of the cover gaskets).
X To avoid a build-up of electrostatic charge,
ATEX - IEC
only use a damp cloth or sponge to clean the
adhesive sticker and equipment.
If during servicing repairs prove to be neces-
sary, section 8 of these operating instructions
will have to be observed.
8 Repairs / Overhaul /
Modification
Repairs and overhaul may only be carried out
with genuine COOPER CROUSE-HINDS /
CEAG spare parts.
Repairs that affect the explosion protection,
may only be carried out by COOPER
CROUSE-HINDS or a qualified electrician
(Competent person) in compliance with the
applicable national rules (IEC/EN 60079-19).
Modifications to the apparatus or changes of its
design are not permitted, except for the
mounting of additional cable entries and the
installation of supply terminals in accordance
with the approval of the apparatus.
To install additional, separately certified
X
ATEX - IEC
supply terminals, the clearance and creepage
distances of EN 60079-7 , table 1 have to be
observed.

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.
