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 hazardous
areas (e.g. EN/IEC 60079-14, NEC, CEC). Non-observance can result in serious
injury and/or damage to the equipment.
For further important safety instructions for instruments with ATEX approval, see
chapter 9 "Information on mounting and operation 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.
WARNING!
To ensure safe working on the instrument, the operating company must ensure
■ that suitable first-aid equipment is available and aid is provided whenever
required,
■ that the operating personnel are regularly instructed in all topics regarding
work safety, first aid and environmental protection, and know the operating
instructions, in particular the section on safety instructions.
WARNING!
When working during a running process operation, measures to prevent
electrostatic discharge from the connecting terminals should be taken, as a
discharge could lead to temporary corruption of the measured value.
Only use the field instrument for earthed thermometers! The connection of a
resistance thermometer (e.g. Pt100) to the TIFxx must be made with shielded
cable. The shield must be electrically connected to the housing of the grounded
thermometer.
