Safety instructions
The operations must be carried
out by electrical suitably trained
in hazardous area with
knowledge of increased safty
explosion protection IEC 60079-14.
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 requirements of the EN 61241-0 and -1
regarding excessive dust deposits and
temperature to be considered from the user.
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.
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 installation switches also fulfil further
requirements such as those of the directive on
electromagnetic compatibility (2004/108/EG).

Field of application
The installation switches 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 aggresive
atmosphere, please refer to manufacturer.
