2 - SAFETY INSTRUCTIONS
This ultrasonic level meter is designed to be installed in a potentially explosive atmosphere due to the presence of gas and dust.
Makesurethatthemarkingofthedevicecomplieswiththeclassicationofthepotentiallyexplosivearea.
Verifythattheinstallationoftheprobedoesnotaectthetypeofprotection.
The device can only be opened under voltage in the absence of a potentially explosive atmosphere, to be checked by
means of an explosimeter.
Incorrect use of the device could cause damage to people, to the product and to the equipment connected to it.
Always respect the plate data for power supply and electrical connections.
3 - INSTALLATION AND COMMISSIONING
Theinstallationmustonlybecarriedoutbyqualiedpersonnel,adequatelytrained,incompliancewiththeregulationsinforce
EN 60079-14.
Theequipmentmustbeusedonlyaerhavingcorrectlyunderstoodtheinstructionsinthisdocument,togetherwiththe
825B105P manuals.
The device must be mounted in such a way as to minimize the risk of shocks to the case and to the sensitive part (transducer).
Useonlythethreadedttingtoinserttheprobeintotheprocess;donotforceinsertionusingthecaseasapivotpoint.
Properly tighten the cable glands and the cover before putting the instrument into operation.
Make sure that the metal case is connected to earth through the appropriate connection.
If it is necessary to replace the cable entries with other similar devices, make sure that the marking of the latter is compatible with the
installation area and the type of protection and that the minimum degree of dust tightness is respected (IP6X).
