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.
