Special conditions for safe use:
1. The transmitters are marked with three options for the indication of the protection code. The
certification is valid only when the protection code is indicated in one of the boxes following the
code.
The following options apply:
•
Ex d IIC T6 ( ) with X ticked in the parenthesis:
The Ex d IIC T6 protection according to certificate Nemko 02ATEX035X /
02ATEX149X applies for the specific transmitter. Certified Ex d IIC cables entries shall be
used.
•
Ex ia IIC T4 ( ) with X ticked in the parenthesis:
The Ex ia IIC T4 protection according to certificate Nemko 03ATEX133X applies for the
specific transmitter. Certified diode safety barriers shall be used.
•
Ex d IIC T6 / Ex ia IIC T4 ( ) with X ticked in the parenthesis:
The transmitter has double protection. Both Ex d IIC T6 and Ex ia IIC T4 protection
apply for the specific transmitter according to certificates Nemko 02ATEX035X/
02ATEX149X and Nemko 03ATEX133X. In this case the transmitter shall be fitted with
appropriate certified cable entries Ex d IIC and the electric circuit supplied by a certified
diode safety barrier as specified for the protection Ex ia IIC T4.
2. For enclosures of the transmitters made of aluminum impact and friction hazards shall be
considered when the transmitter is used in category II 1 G according to EN 50284 clause 4.3.1.
3. The diode safety barrier shall have a linear resistive output characteristic.
4. The pressure of the potentially explosive atmosphere surrounding the transmitter shall be
within the range 0.8 mbar to 1.1 mbar.
