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
