2 Safety instructions GHG 511
plugs and sockets
a
They are not suitable for Zone 0
and Zone 20 hazardous areas.
The temperature class and
explosion group marked on the apparatus
shall be observed.
The electrical connection of the device may
only be carried out by skilled staff
(IEC/EN 60079-14).
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%).
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 sockets may only be used with the
associated Cooper Crouse-Hinds plugs in
undamaged condition.
The interlocking switch of the socket is
mechanically secured and cannot be
connected without plug.
The plugs GHG 543/531 can further on be
inserted with the sockets of the series
GHG 543/GHG531.
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 the
combination of sealing 1 + 2 + 3 for the intermediate region.
