Split-Core, Adjustable Current Switch
with 120VAC/DC Output
quick install
1. Plan the installation:
Locate a mounting surface for the removable mounting bracket that will allow the
monitored conductor to pass through the iris, or "window" when it is installed. Determine
cable routing for the controller connection, allowing wiring to reach the mounting location.
2. Install mounting bracket
Drill holes to mount the bracket to the chosen surface using the included screws.
3. Wire the output connections between the sensor and the controller (solid-state contact).
4. Snap the sensor over the wire to be monitored and clip the assembly to the mounting bracket.
5. Calibrate the sensor (see page 2) with the load running normally.
6. Close up and power up!
