CAUTION:
According to EN 60079-14:2008/12.2.2.3 a) and b) (earthing of cable screens) the metallic
case of ISAS3 must be safely connected to the metallic test structure by two wires of at
least 1.5 mm
2
or one wire of at least 4 mm
2
.
If ISAS3 is to be installed inside a tank of liquid, sloshing forces and peak pressures up to
12 bar must be expected. Provisions have to be made to seal ISAS3 for 12 bar peak
pressure as described in chapter 8.3 ISAS3-SpecIP68 and to protect the sensor case from
sloshing forces, see chapter 8.2 ISAS3-SpecMount.
