Blanking plugs of the types
ATEX - IEC
GGH 960 6107 P**** or GHG 960 1944 R****
may only be used in conjunction with cable
entries of the types GHG 960 92** P**** or
GHG 960 19** R**** .
The following shall be observed when mounting
blanking plugs for COOPER CROUSE-HINDS
metric cable entries (see Fig. 6):
1.
Only the blanking plug associated to
the KLE shall be used.
2.
When closing the gland with a blanking
plug, always use sealing inserts 1+2!.
3. The head of the blanking plug shall,
(3)
as shown in Fig. 6, be on the outside.

-
4. The blanking plug shall be pushed
into the KLE until it reaches the stop.
5. The pressure screw of the KLE shall
be tightened down as described in
6.1.1.
6.1.3
The screw plug shall be screwed tightly into the
threaded hole in the enclosure using a suitable
tool, e.g. 8 mm socket head spanner or a
suitable screw driver.
A counter-nut shall be used for through holes or
Counter-nut
enclosures that are less than 4 mm thick.
An additional seal shall be used for uneven
sealing surfaces.
In general, the M50 screw plug shall be
mounted together with the seal supplied.
6.1.4
A suitable tool, e.g. a fork spanner, shall be used
for mounting the intermediate gland in the
trumpet-shaped gland in such a way that it
cannot twist.
It is necessary to ensure that the gland cannot
twist once the cable has been fed in and the
trumpet-shaped gland mounted (e.g. by using a
counter-nut, see Figs. 7 + 8). A counter-nut shall
be used for through holes or enclosures that are
less than 4 mm thick. When mounting, a seal
shall always be used between the enclosure wall
and intermediate gland (see Fig. 7).

Trumpet-shaped gland
The following describes the mounting of the
cable in the trumpet-shaped gland, as shown in
Fig. 8:
1.
Cut out the individual rings of the
"onion ring" seal insert to match the
respective cable diameter.
2. After feeding in the cable, that has
been cut to length and has the seal
mounted, into the intermediate gland,
screw the trumpet-shaped gland
tightly into the intermediate gland to
seal off the cable.
3. Then mount the pull relief on the
trumpet-shaped gland.
It is necessary to ensure that there is
sufficient pull relief, that damage to the cable
is not possible and that the trumpet-shaped
gland cannot twist.
6.1.5
Reducing gland
A suitable tool, e.g. a fork, ring or box spanner,
shall be used for screwing the reducing gland
tightly into the threaded hole in the enclosure.
A counter-nut shall be used for through holes or
enclosures that are less than 4 mm thick.
An additional seal shall be used for uneven
sealing surfaces.
Screwing several reducing glands one
inside the other to reduce the size of the
entry thread is not permitted.
