*1 When using multiple sensor resistors (or several single resistors) and operating them
simultaneously, the sum of the individual power values must not exceed the value of the max.
permissible power specified in the table.
*2 The minimum neck length is to be defined as the distance between the lower edge of the
connection head and the heat-emitting surface.
*3 When using a transmitter or a current loop signal, the permissible ambient temperature range
is to be taken from the corresponding approval. In each case the lowest temperature level of
the various components used applies.

2.4 Special hazards

WARNING!
Observe the information given in the applicable type examination certificate and the
relevant country-specific regulations for installation and use in potentially explosive
atmospheres (e.g. IEC 60 079-14, NEC, CEC). Non-observance can result in serious
injury and/or damage to equipment. For additional important safety instructions for
insturments with ATEX approval see chapter "7. Notes for mounting and operating in
hazardous areas".
WARNING!
For hazardous media such as oxygen, acetylene, flammable or toxic gases or liquids,
and refrigeration plants, compressors, etc., in addition to all standard regulations, the
appropriate existing codes or regulations must also be followed.
