2.3 Additional safety instructions for instruments with ATEX approval
(TR30-P, TR30-W)
WARNING!
■ Follow the requirements of the 94/9/EC (ATEX) directive.
■ Additionally the specifications of the respective national regulations
concerning Ex-usage (e.g. EN 60079-10 and EN 60079-14) apply.
■ Non-observance of these instructions and their contents may result in the
loss of explosion protection.
■ The responsibility for classification of zones lies with the plant operator and not the
manufacturer/supplier of the equipment.
■ The plant operator guarantees, and is solely responsible, that all thermometers
in use are identifiable with respect to all safety-relevant characteristics. Damaged
thermometers may not be used.
■ Electrical screening may only be grounded at one end, and outside of the Ex area.
Special cases are described in DIN EN 60079-14:2003.
■ There must be a galvanic separation between the intrinsically safe and the
non-intrinsically safe electrical circuits.
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 60079-14, NEC, CEC).
Non-observance can result in serious injury and/or damage to the equipment.
For additional important safety instructions for instruments with ATEX approval
see chapter "2.3 Additional safety instructions for instruments with ATEX
approval".
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!
Protection from electrostatic discharge (ESD) required.
The proper use of grounded work surfaces and personal wrist straps is required
when working with exposed circuitry (printed circuit boards), in order to prevent
static discharge from damaging sensitive electronic components.
