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 product 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 between the sensor and the controller (solid-state
contact).
4. Snap the sensor over the wire to be monitored and push the latch until it is
securely closed. Clip the assembly to the mounting bracket.
5. Calibrate the current switch (see Calibration section).
6. Secure enclosure and reconnect power.
