General The apparatus has to be operated according to the appropriate data in the data sheet and in this instruction manual.
The data stated in the data sheet are restricted by this operating instruction!
The special conditions must be observed!
The ATEX Directive applies only to the use of apparatus under atmospheric conditions.
If you use the device outside atmospheric conditions, consider that the permissible safety parameters should be
reduced.

Details of the correlation between the type of circuit connected, the maximum permissible ambient temperature, the
surface temperature, and the effective internal reactance values can be found on the EC-type-examination
certificate.
The maximum permissible ambient temperature of the data sheet must be noted, in addition, the lower of
the two values must be maintained.

provided in the datasheet.
General The corresponding datasheets, declarations of conformity, EC-type examination certificates, certifications, and
control drawings, where applicable (see datasheets), form an integral part of this document. These documents can
be found at www.pepperl-fuchs.com. The maximum surface temperature of the device was determined without a
layer of dust on the apparatus. Some of the information in this instruction manual is more specific than the
information provided in the datasheet.
