Safety instructions
The plastic or stainless steel
terminal boxes GHG 72. are
not suitable for Zone 0 and
Zone 20 hazardous areas.
The operations must be carried out by
electrical suitably trained in hazardous
area with knowledge of increased safty
explosion protection
IEC 60079-14.
The temperature class and explosion
group marked on the terminal boxes have
to be observed.
Modifications to the terminal boxes or
changes of their design are not permitted.
They shall to be used for their intended
purpose and in perfect and clean condition.
For replacement and repair only genuine
CEAG / CCH spare parts may be used.
The requirements of the EN 61241-0 and -1
regarding excessive dust deposits and
temperature to be considered from the
user.
Prior to taking the terminal boxes into
operation, they shall be checked in
accordance with the instruction as per
section 6.
Before the initial operation, any foreign
matter will have to be removed from the
terminal boxes.
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 apparat is conform to the standards
specified in the EC-Declaration of conformity.
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 terminal boxes also fulfil further
requirements such as those of directive on
electromagnetic compatibility (2004/108/EG).
4
Field of application
The plastic terminal boxes are suitable for
use in Zone 1, 2 and 21, 22
hazardous areas acc. to IEC 60079-10.
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":
- glass-fibre reinforced polyester
- special stainless steel V4 A AISI 316 L
In case of use in an extremely aggresive
atmosphere, please refer to manufacturer
5
Use / Properties
The terminal boxes 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 terminal boxes can also be used in a
„normal industrial area".
