General The apparatus has to be operated according to the appropriate data in the data sheet and in this instruc-
tion manual.
The EU prototype test certificate must be observed.
The special conditions must be adhered to!
Maximum housing surface temperature Die maximale Gehäuseoberflächentemperatur ist der EG-Baumusterprüfbescheinigung zu entnehmen.
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.
The associated apparatus must satisfy at least the requirements of category ia IIB or iaD. Because of the
possibility of the danger of ignition, which can arise due to faults and/or transient currents in the equipoten-
tial bonding system, galvanic isolation in the power supply and signal circuits is preferable. Associated
apparatus without electrical isolation must only be used if the appropriate requirements of IEC 60079-14
are met.
Der eigensichere Stromkreis muss gegen Blitzbeeinflussung geschützt sein.
When used in the isolating wall between Zone 20 and Zone 21 or Zone 21 und Zone 22 the sensor must
not be exposed to any mechanical danger and must be sealed in such a way, that the protective function of
the isolating wall is not impaired. The applicable directives and standards must be observed.
The adhesive label provided must be affixed in the immediate vicinity of the sensor! The surface to which
the label is applied must be clean, flat and free from grease!
The affixed adhesive label must be readable and durable, taking account of the possibility of chemical cor-
rosion!
Maintenance No changes can be made to apparatus, which are operated in hazardous areas.
Repairs to these apparatus are not possible.
[Fett]Special conditions
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 equipoten-
tial bonding.
