Conformity with standards
The safety switches meet the requirements of
EN 50 014, EN 50 018, EN 50 019, EN 50 020
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
intendet for use in potentially explosive
atmospheres.
The safety switches fulfil further requirements
such as those of the ECdirective 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 safety switches are intended for use in
potentially explosive atmospheres in Zones 1
and 2 as well as in Zones 21 and 22 in
accordance with IEC60079-10.
The enclosure materials used, including any
external metal parts, are high quality
materials that ensure a corrosion resistance
and resistance to chemical substances
according to the requirements for use in a
"normal industrial atmosphere":
- glass-fibre reinforced polyester
- impact resistant polyamide
- special steel AISI 316 L
The terminal and bus bar boxes are conform
to the standards specified in the EC-
Declaration of conformity.

Application / Properties
The safety switches are designed for the safe
isolation of the electrical energy at all poles
while maintenance, cleaning and repair work
is being carried out on equipment, machinery
and drives in potentially explosive
atmospheres. See technical data, page 7, for
the temperature class, explosion group and
permissible ambient temperature.
Due to the AC 3 motor switching capacity of
the safety switches, reliable isolation
(switching) is also possible during operation.
