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!
Highest permissible ambient temperature The temperature ranges, according to temperature class, are given in the EU prototype test 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 The sensor must not be mechanically damaged.
When used in the temperature range below -20°C the sensor should be protected from knocks by the pro-
vision 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 equipoten-
tial bonding.
