The operations shall be carried out
by qualified electricians or
suitably trained personnel
according to IEC/EN 60079-14
and engineering/development
specialists according to IEC/EN 60079-0.
The terminal box type S-TB-T are not
suitable for Zone 0 and Zone 20
hazardous areas.
The requirements of the IEC/EN 60079-31
regarding excessive dust deposits and
temperature to be considered by the user.
They shall be used for their intended
purpose and in perfect and clean
condition.
After the terminal box type S-TB-T has been
installed, it shall be tested and fully
certified by a testing authority or
authorized person.
Observe the national safety rules and
regulations for prevention of accidents as
well as the safety instructions included in

Conformity with standards
The terminal boxe type S-TB-T has been
designed, manufactured and tested by
Cooper Crouse-Hinds (CCH), according to
the state of the art and to
DIN EN ISO 9001:2008 and
EN ISO/IEC 80079-34.
The terminal boxe type S-TB-T is conform to
the standards specified in the EC-Declaration
of conformity.
94/9 EC: Equipment and protective systems
intended for use in potentially explosive
atmospheres.
The control units fulfil further requirements,
such as the EC directive on electromagnetic
compatibility (2004/108/EC).

Field of application
The terminal boxes type S-TB-T 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-
quality materials which ensure a corrosion
protection and resistance to chemical sub-
stances corresponding to the requirements in
a "normal industrial atmosphere":
- special stainless steel
- brass
In case of use in an extremely aggresive
atmosphere, please refer to manufacturer.

The terminal boxes type S-TB-T are intended
for the distribution of electrical energy, e.g.
light circuits, heating circuits, control circuits,
intrinsically safe circuits etc.(as to
temperature class, explosion group,
permissible ambient temperature, see
technical data).
The electrical limiting values that are
decisive for the intrinsic safety shall be
observed.
The terminal boxes type S-TB-T can also be
used in a „normal industrial area".
The data as per point 3 and 4 shall be
taken into account with the use.
Applications other than described are not
permitted without COOPER CROUSE-HINDS
/ CEAG´s prior written consent.
For the operation, the instructions stated in
section 7 of the operating instructions will
have to be observed.
The responsibility for the suitability and
proper use of the terminal boxes
type S-TB-T lies with the user.
