Safety instructions
The installation switches are not
suitable for Zone 0 and Zone 20
hazardous areas.
The temperature class and
explosion group marked on the
installation switches shall be observed.
Modifications to the installation switches or
changes of their design are not permitted.
They shall be used for their intended pur-
pose and in perfect and clean condition.
The apparatus shall not be used in dust
layers > 50mm acc. to EN 50 281-1-2.
For replacement and repair only genuine
CEAG spare parts shall be used.
Repairs that affect the explosion
protection, may only be carried out by
CEAG or a qualified electrician in
compliance with the respective national
regulations.
Prior to taking the installation switches
into operation, they shall be checked in
accordance with the instruction as per
section 6.
Before the initial operation, any foreign
matter shall be removed from the
installation switches.
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 installation switches meet the require-
ments of EN 50014, EN 50018, EN 50019 and
EN 50 281-1-1 (comparable international
standards IEC 60079-0, IEC 60079-1,
IEC 60079-7, IEC 60079-11).
94/9/EC: Equipment and protective systems
intended for use in potentially explosive
atmospheres.
The installation switches also fulfil further
requirements such as those of the directive on
electromagnetic compatibility (89/336/EEC).
They have been designed, manufactured and
tested according to the state of the art and to
DIN EN ISO 9001.

Field of application
The plugs and sockets GHG 512 are suitable
for use in Zones 1 and 2 as well as in Zones
21 and 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
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, the additional data on the
employed plastic materials'resistance against
chemicals should be taken from the data sheet
GHG 902 4001 P0001.
