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 distributions GHG 619 are not suitable
for Zone 0 and Zone 20 hazardous areas.
The temperature class and explosion group
marked on the distributions shall be observed.
The requirements of the IEC/EN 60079-31
regarding excessive dust deposits and
temperature to be considered from the user.
The permissible ambient temperature, the
terminal cross section and the self-heating
of the apparatus, that is mainly caused by
the power dissipation are to be observed to
ensure that the temperature class stated on
the type label of the apparatus is main-
tained. (Test criterion for the self-heating is
an overload of 10%).
The user shall ensure that the overall current
of the bus-bar system ddoes not exceed the
nominal current of the respective system
(250 A / 315 A).
The apparatus shall be used for the intended
purpose and shall be in a perfect and clean state.
Prior to being put into operation, the
distributions shall be checked in accordance
with the instructions given in section 6.
Before opening the enclosures, it is
necessary to ensure that the distributions
are isolated from the voltage supply or take
the appropriate protective measures.
The minimum terminal cross sections of the
flameproof components shall be observed
during connection in acc. with IEC/EN 60204-1.
When using a bus-bar system, it is neces-
sary to ensure that the surge short-circuit
current of the mains supply does not exceed
the respective value of the busbar system
used
(315 A -> Is = 47 kA,
250 A -> Is = 35 kA).
The minimum degree of protection IP 54 is no
longer guaranteed when the MCB-flap is open.
The flap shall be closed again immediately
after actuating the components, whereby
the red lock position indicator shall be fully
visible under the window.
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 (CCH) /
EATON plugs in undamaged condition.
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.

Conformity with standards

The apparatus are conform to the standards
specified in the Declaration of conformity,
enclosed separately�
References to standards and directives in these
operating instructions always relate to the latest
version� Other additions (e�g� details relating to
the year) shall be observed�

Field of application

The distributions are suitable for use in
hazardous areas in Zones 1, 2 and Zones 21
and 22 in acc� with IEC/EN 60079-10-1 and
IEC/EN 60079-10-2�
The grey plastic empty enclosures with colour
code RAL 7035 are suitable for use in
hazardous areas in zones 1and 2 acc� with
IEC 60079-10-1 after authorized�
The materials used for the enclosures, including
the exterior metal parts, are high quality
materials that ensure an appropriate corrosion
protection and resistance to chemical
substances according to the requirements for
use in a "normal industrial atmosphere":
– impact-resistant polyamide
– polyester reinforced with glass fibre
– polyester reinforced with glass fibre grey
RAL 7035
– stainless steel V2A
– stainless steel V2A powder-coated
– stainless steel V4A
– stainless steel V4A powder-coated
– steel powder-coated
In case of use in an extremely aggressive
atmosphere, please refer to manufacturer�
