WARNING
Coaxial transducer cable extension
Do not use a coaxial transducer cable extension with the SITRANS LUT400. High voltage
transmitted on shield of coaxial cable could result in personal injury, damage to equipment,
or poor device performance.

WARNING
Hazardous voltage
Hazardous voltage present on transducer terminals during operation
.
Note
•
Do not connect coaxial cable directly to SITRANS LUT400 due to high voltage
transmitted on shield of coaxial cable.
•
Do not connect the LUT400 shield and white transducer wires together; wire to separate
terminals.
•
Disregard older transducer manuals that recommend these practices.
