diameter be used.
After having mounted the cable, the coupling
N
ring, fig. 6, item 4, is to be screwed fingertight
until the sealing effect is obtained. Then the
PE
screws, fig. 6, item 5, of the pull-relief, fig. 6,
item 6, are to be tightened down.
Mind! Overtightening might impair the
pull-relief effect!

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 equipoten-
tial 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 war-

Maintenance / Servicing
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 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.
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..

Repair/Overhaul / Modifica-
tions
Repairs and overhaul may only be carried out
with genuine Eaton's Crouse-Hinds Business /
CEAG 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 Eaton / CEAG for repair.
Repairs that affect the explosion protection,
may only be carried out by Eaton / CEAG 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
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.
