The tests of clamping ranges and torque values were performed with metal mandrel. The clamping range can
vary by using cables with different manufacturing tolerances and material properties. Please use a suitable
combination of seals in the intermediate area, so that the cap nut can be tightened in future maintenance
work on the cable entry.

Safety instructions
Target group:
For skilled electricians and suitable
qualified, instructed personnel in
accordance with national legislation,
including the relevant standards and, where
applicable, in acc. with IEC/EN 60079-14 on
electrical apparatus for explosive atmospheres.
The multiple plug and socket systems 7-pole
(GHG 511 .7. / GHG 592) and 21-pole (GHG
511 .9 / GHG 591) are not suited for use in
Zone 0.
The operations must be carried out by
electrical suitably trained in hazardous area
with knowledge of increased safety
explosion protection IEC/EN 60079-14.
The temperature class and type of
protection stated on the apparatus shall
be observed.
To ensure adherence to the temperature
class stated on the type label of the
apparatus, the permissible ambient
temperature, the rated terminal cross
section and the self-heating of the appara-
tus, that
is mainly due to the power dissipation, shall
be taken into account (test criterion for the
self-heating is an overload of 10%).
Modifications or changes to the plug and
socket systems are not permitted.
They shall be used for their intended
purpose and in a perfect and clean state.
Prior to being put into operation, the plug
and socket systems shall be checked in
accordance with the instructions as per
section 6.
The sockets may only be used with the
associated COOPER CROUSE-HINDS plugs
in undamaged condition.
The 7-pole wall socket is safeguarded by an
interlocking switch and can, therefore, not
be switched on if the plug is not inserted.
The plug of the 21-pole plug and socket may
not be inserted into the 21-pole sockets and
coupler or withdrawn from them while they
are live (see also section 5).
Before initial operation, any foreign matter
shall be removed from the apparatus.
The national safety rules and regulations
for the prevention of accidents, as well as
the safety instructions included in these
operating instructions, that, like this text,
are set in italics, shall be observed!
