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 GHG 512 plugs and sockets are not
suitable for Zone 0 and Zone 20 hazardous
areas. The temperature class and explosion
group marked on the apparatus shall be
observed.
Modifications to the plugs and sockets or
changes of their design are not permitted.
They shall be used for their intended
purpose and in perfect and clean condition.
The requirements of the IEC/EN 60079-31
regarding excessive dust deposits and
temperature to be considered from the user.
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 apparatus
that is mainly due to the power dissipation
shall be taken into account (test criterion for
the self heating is an overload of 10%).
For replacement and repair only genuine
COOPER CROUSE-HINDS spare parts shall
be used.
Repairs that affect the explosion protection,
may only be carried out by COOPER
CROUSE-HINDS or a qualified electrician in
compliance with the respective national
regulations.
Prior to taking the plugs and sockets into
operation, they will have to be checked in
accordance with the instruction as per
section 6.
The interlocking switch of the socket is
mechanically secured and cannot be
connected without plug.
The sockets may only be used with the
associated COOPER CROUSE-HINDS plugs
in undamaged condition.
The plugs GHG 532 can further on be inserted
with the sockets of the series GHG 532.
Before the initial operation, any foreign
matter will have to be removed from the the
plugs and sockets.
Flange sockets may only be used in
protective enclosure or apparatus that have
been certified for the respective application.
Observe the national safety rules and
regulations for prevention of accidents as
well as the safety instructions included in
these operating instructions and set in
italics the same as this text!

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.
