Stripping and Connecting Terminals
1. Cut into the Sensing Band approximately 4 to 6 cm in from the end as shown in the diagram below.
2. Strip away approximately the last 9 mm of the sheath to expose the core (SUS line).
3. To connect to the Terminal Block, push down the top of the terminal with a screwdriver* and insert the core from the side. More Sensing Bands
can be connected simply by wiring in an arch shape.
Note: When you are finished working, sufficiently confirm that there is an electrical connection.
* You can use a commercially available screwdriver, but we recommend either 1) a 210-350/01 Screwdriver or 2) a 209-132 Operating Tool from

* Use a class 2 power supply for the DC power supply if UL/CSA or CE Marking
compliance is required.
Note: Always use a 3-conductor cable for wiring and connect to terminals 2, 3,
and 4 on the Unit. Connect the Sensing Band between terminals 2 and 4.
