SITRANS LR250 (PROFIBUS PA)
Operating Instructions, 01/2014, A5E32221386-AB

Installing/mounting

WARNING

•

Installation shall only be performed by qualified personnel and in accordance with local

governing regulations.

•

Handle the device using the enclosure, not the process connection tag, to avoid

damage.

•

Take special care when handling the threaded PVDF and Flanged encapsulated

antennas. Any damage to the antenna surface, particularly to the tip/lens, could affect

performance.

•

Materials of construction are chosen based on their chemical compatibility (or inertness)

for general purposes. For exposure to specific environments, check with chemical

compatibility charts before installing.

Note

•

For European Union and member countries, installation must be according to ETSI EN

302372.

•

Refer to the device nameplate for approval information.
