Comment on :
If the signal circuit (active or passive) is situated in Zone 21 or Zone 22 and the electrical connection is protected by means of
suitable measures against mechanical damage (short-circuit / interruption), the values for the inner and permitted outer
inductances and capacitances corresponding to material group IIB do not have to be taken into consideration.
The measure for energy limitation by means of intrinsic safety (ia or ib, depending on the application) is not affected by this.
