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.
Parts of the rod-antenna and the All PTFE antenna are non-conducting and
the area of the non-conducting part exceeds the maximum permissible areas
for Group IIC according to EN 50014 clause 7.3 (20 cm
2
) and Category II 1 G
according to EN 50284 clause 4.4.3 (4 cm
2
). Therefore, when the antenna 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 and part of antennas exposed to the
exterior atmosphere of the tank is made with light metal alloys and used in
category II 1 G.
