2 Safety Instructions according to Directive 94/9/EC
The transducers
**K1N41, **G1N41, **K1N43, **G1N43, **H1N43, **M2N41,
**P2N41, **M1N43, **P1N43, **M2E45, **P2E45, **K1N81,
**G1N81, **K1N83, **G1N83, **H1N83, **M2N81, **P2N81,
**M1N83, **P1N83, **K1LI1, **G1LI1, **M2LI1, **P2LI1,
**M2E85, **P2E85, **Q2E85, **Q2N81, **Q1N83
must always be used in the delivered transducer shoe to protect
them against mechanical stress.
If an equipotential bonding of the transducers is necessary, the
ground terminal of the transducer housing and/or of the transducer
shoe has to be used.
The transducers must be connected with the flowmeter only if there is
no risk of an explosive atmosphere or if the flowmeter is not connect-
ed with the power supply.
When using the transducers in areas with combustible dust (zone
21), the max. surface temperature TX = T
RB
+ 5 K (T
RB
- surface
temperature of the pipe or vessel on which the transducer is
mounted).
