WARNING<br />
Due to the creation of a permanent grounding point between<br />
the sensor’s transducer cover and the mounting ring when<br />
the sensor is installed, the <strong>2150EX</strong> system can not<br />
withstand the 500 VAC test according to EN60079-11:2007<br />
clause 6.3.12. Refer to IEC 60079-14, section 12.2.4,<br />
regarding earthing of intrinsically safe circuits.<br />
WARNING<br />
The sensor mounting ring is a potential isolated charge<br />
carrier. Your installation MUST satisfy earthing<br />
requirements. Refer to IEC 60079-14 section 12.2.4 and IEC<br />
60079-11.<br />
