Cables

The SITRANS LUT400 is designed to work with two conductor shielded transducer cables.
Connection
mA output, sync,
Temperature sensor,
discrete input
Transducer
Relay output AC input Copper conductors per local requirements.
Preferred shielding is braided shield.
1)
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.
5.1.4

Transducers

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.
