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.
