2.1 Safety instructions

a
The operations must be carried
out by electrical suitably trained
in hazardous area with knowledge
of increased safty explosion protection and
IEC/EN 60079-14.
The terminal boxes GHG 791 are not suitable
for Zone 0 and Zone 20 hazardous areas.
The temperature class and explosion group
marked on the terminal boxes shall be
observed.
The requirements of the IEC/EN 60079-31
regarding excessive dust deposits and
temperature to be considered from the user.
Modifications to the terminal boxes or
changes of their design are not permitted.
They shall be used for their intended
purpose and in perfect and clean condition.
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!

Conformity with standards

The apparatus is conform to the standards
specified in the EU-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 terminal boxes GHG 791 01 and GHG 791
02 are suitable for use in Zone 1 and 2 as well
as in Zones 21 and 22 hazardous areas acc. to
IEC/EN 60079-10-1 and IEC/EN 60079-10-2 !
The enclosure materials employed, including
the exterior metal parts, are made of high-quali-
ty materials which ensure a corrosion protec-
tion and resistance to chemical substances
corresponding to the requirements in a "normal
industrial atmosphere":
– impact resistant polyamide
– special steel AISI 316 L
In case of use in an extremely aggressive
atmosphere, please refer to manufacturer.
5 Use / Properties
The terminal boxes are intended for the distribu-
tion of electrical energy e.g. light circuits, heater
circuits, control circuits, intrinsically safe circuits
etc. in hazardous areas (see technical data).
The temperature class, explosion group and
permissible ambient temperature, see technical
data.
The electrical limiting values that are
decisive for the intrinsic safety shall be
observed.
The data as per point 3 and 4 shall be taken
into account with the use.
Applications other than described are not
permitted without EATON / COOPER
CROUSE-HINDS's prior written consent.
For the operation, the instructions stated in
section 7 of the operating instructions shall
be observed.
The user alone is responsible for the
appropriate use of this terminal box in
consideration of the basic conditions
existing at the plant (see technical data).

Installation

For the mounting and operation, the respective
national regulations (e. g. Betr.Si.V, equipment
safety law for Germany) as well as the general
rules of engineering shall be observed
(IEC/EN 60079-14).
