Installation
The SITRANS LU SAM should be mounted in an area that is within the unit’s ambient
temperature range and suitable for the specified enclosure. The front cover should be
accessible for viewing and have sufficient room to swing open; allowing for wiring and
setting switches.
The SITRANS LU SAM may be installed remotely from the main electronics to a maximum
loop length of 3,000 m (10,000 ft) when using 18 ga. wire.
Outline and Mounting
Notes
• Installation shall only be performed by qualified personnel and in accordance
with local govering regulations.
• Do not mount the SITRANS LU SAM in direct sunlight without the use of a sun
shield.
• This product is susceptible to electrostatic shock. Follow proper grounding
procedures.
Note: Non-metallic enclosure does not provide grounding between connections.
Use grounded type bushings and jumpers.

SITRANS LU 10 Communication
Retransmit Configuration
* Serial Configuration (single loop)
1. SITRANS LU SAM receiver input is polarized.
2. Refer to associated application device instruction manual for wiring detail. Check
that the communication parameter P-740, is ‘on’.
3. SITRANS LU SAM interconnecting cable shield should be grounded at applications
device only. Insulate shields at junctions to prevent inadvertent grounding.
4. * If SITRANS LU SAM is unpowered, transmitter ceases communication to all
downstream peripherals.
5. Maximum individual loop length 3000 m (10,000 ft) with specified cable.
