INSTALLATION
Disconnect and lock out power to the enclosure containing the
conductor to be monitored.
1. Locate a mounting surface for the removable mounting bracket that will allow
the monitored conductor to pass through the center window when it is installed
and that will keep the device at least 1/2” from any uninsulated conductors.
Determine cable routing for the controller connection, allowing wiring to reach
the mounting location.
2. Drill holes to mount the bracket to the chosen surface using the included screws.
3. Wire the output connections and relay between the sensor and the controller
(solid-state contact).
4. Route the conductor through the sensor’s center window and slip the assembly
into the mounting bracket.
5. Secure enclosure and reconnect power.
6. Calibrate sensor with load running normally.
