Safety instructions
Warning: These operating
instructions may only be used in
conjunction with the instructions
GHG 660 7003 P0004.
The explosion-protected enclosures and
distributions are not suited for use in
Zone 0 and Zone 20.
The requirements of the EN 61241-0 and -1
regarding excessive dust deposits and
temperature to be considered from the user.
The electrical connection of enclosures
and distributions may only be carried out
by elektronik specialists acc to EN 60079-14.
It is necessary to ensure that the power
dissipation of apparatus is not exceeded
(see technical data, page 8).
The temperature class and explosion group
stated on the apparatus and distributions
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
apparatus mainly due to the power
dissipation shall be taken into account
(test criterion for the self heating is an
overload of 10%).
Modifications or design changes to
apparatus and distributions that affect the
explosion protection are not permitted.
They shall be used for their intended purpose
and shall be in a perfect and clean state.
Only original Cooper Crouse-Hinds /
CEAG parts may be used as replacements
and for repairs.
Repairs that affect the explosion protection
may only be carried out by Cooper
Crouse-Hinds / CEAG or by a qualified
electrician in compliance with the
respective national regulations.
Prior to being put into operation, the
boxes shall be checked in accordance with
the instructions as per section 6.
The operator is required to ensure that the
overall current of a distribution with bus
bar systems does not exceed the values
stated in the technical data of the bus bar
boxes.
Distributions mounted on a floor frame
shall be safeguarded against falling over.
Before initial operation, any foreign matter
shall be removed from the apparatus.

Cooper Crouse-Hinds GmbH
Explosion-protected flameproof enclosures and
distributions, Series: GHG 6..
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!
3
Conformity with standards
The apparat is conform to the standards
specified in the EC-Declaration of conformity,
enclosed separately.
It has been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001
94/9 EC: Equipment and protective systems
intended for use in potentially explosive
atmospheres.
The apparats fulfil further requirements, such
as the EC directive on electromagnetic
compatibility (2004/108/EC)
4
Field of application
The flameproof enclosures and distributions
are intended for use in potentially explosive
atmospheres in zones 1, 2 and 21, 22 in
accordance with EN/IEC 60079-10!
The enclosure materials used, including any
external metal parts, are high quality materials
that ensure a corrosion resistance and
resistance to chemical substances according
to the requirements for use in a "normal
industrial atmosphere":
- sheet steel and plastic powder coating
- stainless steel AISI 316 L
- aluminium alloy pressure casting
- galvanized steel.
Optionally, a surface protection for tropical
and sea climates, etc. is also available for use
in extremely aggressive atmospheres.
5
Use / Properties
The enclosures and distributions are used for
safeguarding, controlling, indicating, isolating
the electrical energy and the power supply of
electrical installations, machines and drives,
etc. in potentially explosive atmospheres. The
temperature class, explosion group and
permissible ambient temperature can be
found in the technical data.
If the enclosures and distributions
contain intrinsically safe circuits or Ex-i
components, the electrical limiting values
that are decisive for the "Intrinsic Safety"
shall be observed.
Within the scope of the approvals, these
flameproof enclosures may be mounted
together on wall or floor frames using bus bar
boxes of the series "GHG 75. .." to form
distributions according to the building-block
principle.
Warning: The maximum length of the
distribution shall not exceed 6.00 m,
whereby it is essential that the
information given in the instructions for
bus bar boxes GHG 660 7003 P0004 be
taken into account.
Die Mindestspaltlängen nach EN 60079-1
dürfen nicht unterschritten werden.
Wird die Schauscheibe d= 80 mm verwen-
det, müssen mindestens 6 Gewindegänge
im Eingriff sein.
Veränderungen an den Spaltlängen oder
Spaltweiden dürfen ohne Rücksprache
mit CCH nicht vorgenommen werden.
The data according to sections 3 and 4
shall be taken into account during use.
Applications other than those described
are not permissible without a written
declaration of consent from Messrs.
Cooper Crouse-Hinds / CEAG.
During operation the instructions stated
in section 7 of the operating instructions
shall be observed.
The sole responsibility with respect to the
suitability and proper use of these boxes
lies with the operator.
6
Installation
Only fully certified enclosures or
distributions may be installed and put into
operation.
The relevant national regulations and the
generally recognized rules of engineering
apply for the installation and operation.
The improper installation and operation of
enclosures can result in the invalidation of
the guarantee.

Mounting
When the flameproof enclosures and
distributions are mounted directly onto the
wall or onto wall or floor frames, they shall
rest evenly only on the fastening points
provided for this purpose.
In order to be able to open the covers of
flameproof enclosures faultlessly, it is
absolutely essential to ensure that the
flameproof enclosures are assembled
without twisting (see technical data for test
torques).
Fixing dimensions are shown in the dimension
drawings on pages 8 and 9.
