Special Conditions for Safe Use (X):
1. The intrinsically safe circuits do not withstand the 500V AC test as
specified in EN 60079-11:2012 clause 6.3.13.
2. Potential ignition hazards by impact or friction need to be considered
according to EN 60079-0:2012 clause 8.3 (for EPL Ga and EPG Gb), and
clause 8.4 (for EPL Da and EPL Db), when the transmitter enclosure and
antennas exposed to the exterior atmosphere of the tank, is made
with light metals containing aluminium or titanium. The end user shall
determine the suitability with regard to avoid hazards from impact and
friction.
3. Parts of the sensor probes, for type 5300 are non-conducting material
covering meatal surfaces. The area of the non-conducting part
exceeds the maximum permissible areas for Group III according to EN
60079-0.2012 clause 7.4:3. Therefore, when the probe is used in a
potentially explosive atmosphere group III, EPL Da, appropriate
measures must be taken to prevent electrostatic discharge.
4. The Ex ia version of model 5300 FISCO device may be supplied by an
“Ex ib” FISCO power supply, when the power supply is certified with
three separate safety current limiting devices and voltage limitation
which meets the requirements for type Ex ia.
5. 1/2” NPT threads need to be sealed for dust and water ingress
protection, IP 66, IP 67 or “Ex t”, EPL Da or Db is required.
