Specific Conditions for Safe Use (X):
1. The intrinsically safe circuits do not withstand the 500V AC test as specified in
EN 60079-11clause 6.4.13.
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 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
EN 60079-0:2012 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 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.
