6.1.6 Drain plug
A suitable tool, e.g. a fork, ring or box spanner,
shall be used for screwing the drain plug tightly
into the threaded hole in the enclosure.
An additional seal shall be used for uneven
sealing surfaces.
The drain plug shall be mounted at the lowest
point of the apparatus or enclosure (see Fig. 9).
The minimum wall thickness may not be
less than 4 mm.
Entry components shall be screwed in tightly to
ensure the specified minimum degree of
protection (see Technical Data for test torques).
Overtightening can impair the degree of
protection.

6.2 Putting into operation

Prior to putting the mounted entry components
into operation, the tests specified in the
individual national regulations shall be per-
formed.
In addition to this, prior to putting the entries into
operation, the correct mounting shall be checked
in accordance with these operating and
mounting instructions and any other applicable
regulations.
In locations where they are particularly
at risk, the entries shall be safeguarded
against being torn out of the apparatus or
enclosure walls by external mechanical
influences (e.g. by fork lift trucks, by knocking
or similar).

Maintenance / Servicing

The valid national regulations for the
servicing / maintenance of electrical
apparatus for use in potentially explosive
atmospheres shall be observed
(e.g. IEC/EN 60079-17).
The necessary intervals between servicing
depend upon the specific application and shall be
stipulated by the operator according to the
respective operating conditions.
As part of the routine testing, above all, parts on
which the explosion protection depends shall be
checked ( e.g. intactness of entry components
and seals).
Pressure screws of cable entries, trum-
pet-shaped glands of trumpet-shaped cable
entries shall be checked at regular intervals to
ensure that they are screwed in tightly and, if
necessary, they shall be tightened down.
If, in the course of servicing, it is ascertained,
that repairs are necessary, section 8 of these
operating instructions shall be observed.

Repairs / Modifications

Only original COOPER CROUSE-HINDS parts
shall be used for carrying out repairs that
concern the explosion protection.
Repairs that affect the explosion
protection may only be carried out by
COOPER CROUSE-HINDS or by a qualified
electrician in compliance with the respective
national regulations (e.g. IEC/EN 60079-19).
Modifications to the entry components are not
permitted.

Disposal / Recycling

The respective valid national regulations for
waste disposal shall be observed when
disposing of apparatus.
To facilitate recycling of individual parts, parts
made of moulded plastic bear the marking for
the type of plastic used.
The product range is subject to changes and
additions.
