Emerson Rosemount 5300 Series - Page 365

Special Conditions for Safe Use (X):
1. 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.
2. 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 III
according to IEC 60079-0.2011 clause 7.4:3 Therefore, when the antenna is used in
a potentially explosive atmosphere group III, EPL Da, appropriate measures must be
taken to prevent electrostatic discharge.
3. 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.
