Special Conditions for Safe Use (X):
The intrinsically safe circuits do not withstand the 500V AC test as specified in
EN 50020 clause 6.4.12.
Probes covered with plastic and/or with plastic discs will have a
non-conducting area that exceeds the maximum permissible areas for Group
IIC and Category II 1G according to EN 50284 clause 4.4.3 (4 cm
2 ).
Therefore, when the probe is used in a potentially explosive atmosphere,
appropriate measures must be taken to prevent electrostatic discharge.
Impact and friction hazards need then to be considered according to EN
50284 clause 4.3.1 when the transmitter exposed to the exterior atmosphere
of the tank is made with light metal alloys and used in category II 1 G.
