Special Conditions for Safe Use (X):
1. The Intrinsically safe circuits do not withstand the 500 V AC test as
specified in IEC 60079-11 clause 6.3.13
2. Potential ignition hazards by impact or friction need to be considered
according to IEC 60079-0:2011 clause 8.3 (for EPL Ga and EPL Gb) and
clause 8.4 (for EPL Da and EPL Db), when the transmitter enclosure and
antenna exposed to the exterior atmosphere of the tank, is made with
light metals containing aluminum 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 the type 5300 are non-conducting and
the area of the non-conducting part exceeds the maximum
permissible areas for Group IIC and according to IEC 6079-0.2011
clause 7.4: 20 cm
2
for EPL Gb and 4 cm
2
for EPL Ga. Therefore, when
the antenna is used in a potentially explosive atmosphere, appropriate
measures must be taken to prevent electrostatic discharge.
4. The Ex ia version of model 5300 FISCO field 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. ½” 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.
