Reference value of a circuit: C ≈ 200 nF/km, L ≈ 1 mH/km (C ≈ 200 pF/m, L ≈ 1 µH/m)
Mounting of the sensors
The execution of the installation of the intrinsically
safe circuits is to be realized according the up-to-
date European standards EN 60 079-14:2003 or
EN 61 241-14:2004.
Attention:
Acc. to EN 60 079-11:2007 the following is to be considered
at the installation: The distance of ≥ 6 mm between the terminals of
the intrinsically safe circuits to other intrinsically safe circuits should
be considered. The distance of ≥ 50 mm between the terminals of the
intrinsically safe circuits to other not intrinsically safe circuits should be
considered.
Initiation and installation are to be accomplished only by therefore quali-
fied personnel.
