2.4 Special hazards

WARNING!

Observe the information given in the applicable type examination certicate and

the relevant country-specic 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, ammable 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 rst-aid equipment is available and aid is provided whenever

required,

■

that the operating personnel are regularly instructed in all topics regarding

work safety, rst 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 eld 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.
