Installation
The relevant national regulations and the
generally recognized rules of engineering apply
for the installation and operation.
(IEC/EN 60079-14).
The improper installation and operation
of enclosures can result in the invalidation of
the guarantee.
Observe the special operational condi-
tions accordance to IEC/EN 60069-14.
X
Only fixed cables may be used. The operator
ATEX - IEC
shall ensure that an appropriate strain relief is
provided. This is not required for trumpet-shaped
glands.
X
The degree of protection IP66 is only
ATEX - IEC
Through
attained if the seals and cable entries are
hole
installed correctly.
X
Cable entries that are only suited for a low
ATEX - IEC
impact energy shall be built into an enclosure in
such a way as to protect them from a mechani-
cal impact energy.

6.1 Mounting
Prior to mounting, ensure that the
threads of the entry components match the
threads of the apparatus or enclosure.
If the entries and components are to be
screwed directly into the walls, the wall thick-
ness of the apparatus shall be at least
Counter-nut
4 mm.
Counter-nuts shall be used if enclosure
walls are less than 4 mm thick. The minimum
"uneven"
thickness of the enclosure wall shall be
sealing surface
1.5 mm.
The use of entry elements with damaged
or dirty threads can impair the IP degree of
protection.
Imported Cables and wiring shall be
with seal
relieved of tensile forces (eg with a cable
clamp).
6.1.1
Cable entries (KLE)
The intermediate gland (see Fig. 1) of the cable
entries shall be fitted with a suitable tool, e.g.
fork, ring or box spanner.
It is mounted directly in the threaded hole or via
the through hole of the enclosure (see Fig. 2).
If the sealing surfaces are uneven, seals shall be
used between the enclosure wall and the
intermediate gland (see Fig. 3).
Counter-nuts shall be used for walls with a
thickness of less than 4 mm (see Fig. 2).
Cables are fed in as shown in Fig. 4.
The seal inserts shall be chosen to suit the
respective cable diameter
(Page 13 Figs. A, B, C and D).
Use COOPER CROUSE-HINDS spanners with a
side opening can be used to facilitate the
tightening of the pressure screw when the cable
entry has been mounted (see Fig. 5).
Order No. GHG 960 1951 R0001 for
Set 1 (M12, 16, 20, 25, 32 and 40)
Order No. GHG 960 1951 R0002 for
Set 2 (M50 and M63)
To ensure the required minimum degree of
protection, the gland body and the pressure cap
shall be tightened with the given test torques
(see Technical Data).
When tightening the pressure cap, the gland
body shall be prevented from turning with a
suitable tool, e.g. a spanner.
Overtightening can impair the degree of
protection.
Optionally, cable entries with colour-coded (light
blue) pressure screws can be used for
intrinsically safe circuits
(see main COOPER CROUSE-HINDS catalogue
for order numbers).
