 E3NW-DS Sensor Distributed Sensor Units
Connect the D+ and D− lines and the shield wire in the communications cable to the power 
supply/communications connector on the Distributed Sensor Unit. Also, clamp on a ferrite core 
(enclosed) on the communications cable.
In connections between Distributed Sensor Units, connect the shield wire in the communications 
cable to the −V terminal on only one of the Distributed Sensor Units. Do not connect the shield wire 
to both Units.
