is connected.
Note:
This symbol stresses important information.
2.1 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 terminal boxes GBX 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 from the user.
The temperature class and explosion group marked on the terminal
boxes have to be observed.
Changes of the design and modifications to the apparatus are not
permitted!
They shall be used for their intended purpose and in perfect and
clean condition.
Prior to being put into operation, the apparatus shall be checked in
accordance with the instructions as per section 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!

Conformity with standards
The explosion protected terminal boxes are 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 are suitable for use in Zone 1, 2 and 21, 22 hazardous
areas acc. to IEC/EN 60079-10-1 and EN/IEC 60079-10-2.
The enclosure materials used, including any external metal parts, are
high quality materials which ensure a corrosion protection and resistance
to chemical substances corresponding to the requirements in a "normal
industrial atmosphere":

Explosion-protected terminal boxes GBX
In case of use in an extremely aggressive atmosphere, you can obtain
information concerning the chemical resistance of the materials used
from your Cooper Crouse-Hinds branch.

The terminal boxes are intended for the distribution of electrical energy
e.g. light circuits, heater circuits, control circuits, intrinsically safe circuits
etc. in hazardous areas (see technical data).
The data as per point 3 and 4 shall be taken into account with the
use.
Applications other than those described are not permitted
without Cooper Crouse-Hinds's / EATON's prior written consent.
The instructions stated in section 7 of the operating instructions
shall be observed during operation.
The user alone is responsible for the appropriate use of this
junction box in consideration of the basic conditions existing at the
plant (see technical data).
The product is protected by patents. For more information, please contact
your local Cooper Crouse-Hinds / EATON representative.

For the mounting and operation, the respective national regulations as
well as the general rules of engineering will have to be observed
(IEC/EN 60079-14).
The enclosure is mounted through the screw channels lying outside the
sealing space.
In the case of enclosures that have to be set up outside, it may be
necessary to take measures to ensure that operation is in accordance
with the intended use. This would include, for example, roofs as
protection against rain or outer housings with an adequate protection
class.
Enclosures shall be mounted horizontally over the wall or on the
horizontal surfaces.
The chosen screw shall match the fastening hole (see dimensional
drawing) and it must not damage the hole (e. g. use of a washer).
If the screws are overtightened, the apparatus can be damaged.
6.1
Ensure and take suitable precautions before opening the housing
voltage.
Before opening the housing to make sure that no explosive atmos-
phere environment.
Unscrew cover fixing screws with a suitable screwdriver.
Enclosure cover is not safeguarded against falling down.
