Emerson Rosemount 5300 Series - Page 363

II 1D Ex ia IIIC T69 °C/T79 °C Da, (-50 °C ≤ Ta ≤ +60 °C /+70 °C)
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
metal 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. 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.
