General The apparatus has to be operated according to the appropriate data in the data
sheet and in this instruction manual. The EU prototype test certificate must be
observed. The special conditions must be adhered to!
Directive 94/9EG and hence also EC-Type Examination Certificates apply in
general only to the use of electrical apparatus under atmospheric conditions
The use in ambient temperatures of > 60 °C was tested with regard to hot sur-
faces by the mentioned certification authority.
If the equipment is not used under atmospheric conditions, a reduction of the
permissible minimum ignition energies may have to be taken into consideration.
Highest permissible ambient temperature The temperature ranges, according to temperature class, are given in the EC-
Type Examination Certificate.
Installation, Comissioning Laws and/or regulations and standards governing the use or intended usage
goal must be observed. The intrinsic safety is only assured in connection with
an appropriate related apparatus and according to the proof of intrinsic safety.
Maintenance No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
Special conditions
Protection from mechanical danger When used in the temperature range below -20°C the sensor should be pro-
tected from knocks by the provision of an additional housing.
Electrostatic charging Electrostatic charges must be avoided on the mechanical housing components.
Dangerous electrostatic charges on the mechanical housing components can
be avoided by incorporating these in the equipotential bonding.
