Specific Conditions for Safe Use (X):
1. The intrinsically safe circuits do not withstand the 500V AC test as specified in IEC
60079-11 clause 6.4.13.
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 antennas 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. The antennas for type 5400, are non-conducting and the area of the non-conducting
part exceeds the maximum permissible areas for Group IIC and according to IEC
60079-0 .2011 clause 7.4: 20 cm2 for EPL Gb and 4 cm2 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 5400 may be supplied by an Ex ib certified safety barrier. The
whole circuit shall then be regarded type Ex ib.
The preferred type Ex ia or Ex ib shall be indicated on the marking label as specified in
the instructions for the transmitter. The antenna part, located in the process vessel, is
classified EPL Ga and electrically separated from the Ex ia or ib circuit.
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.
