6.3 Cable entries (KLE);
blanking plugs
Generally, only certified cable entries and
blanking plugs may be used.
Trumpet-shaped cable glands or other
suitable entries with additional pull-relief
shall be used for flexible cables.
When using cable entries with a lower IP
protection than that which applies to the device
(see page 7+8, technical data), the IP
protection of the whole device is reduced.
The mounting directives applicable to the cable
entries used shall be observed.
Unused holes shall be sealed with a certified
blanking plug in order to establish the minimum
protection category.
In case of sealing inserts that are cut out, it is
necessary to ensure that the insert is properly
adapted to the cable diameter.
When fitting the cable entries, taken that the
sealing inserts are case shall be appropriate for
the cable diameter.
In order to ensure the required minimum
protection category, the cable glands shall be
tightened down.
Overtightening might impair the protection
category.
All vacant metric Cooper Crouse-Hinds / EATON
cable entries shall be closed with the certified
blanking plug for metric cable entries.
Attention: Metal flanges, metal plates and
metal cable glands shall be included in the
equipotential earth connection.

Taking into operation

Prior to taking the apparatus into operation,
the tests specified in the relevant national
regulations shall be carried out. In addition to
this, 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 damage before inserting
it into the socket.
The user must ensure that a uniform equipoten-
tial earth applies throughout when the plug and
socket system is being operated.
The incorrect 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 atmos-
pheres, 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 have to be,
therefore, determined by the user dependent
on the conditions of use.
When servicing the plugs and sockets,
particularly those parts that are decisive for the
type of protection against explosion, will have
to be checked (e. g. intactness of flameproof
-encapsulated components and housing, firm fit
of the cable entries and efficacy of gaskets).
If, during servicing, the needd to carry out repair
work is determined, section 8 of these
operating instructions will have to be observed.
