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. Route the conductor through the sensor’s center window and slip the assembly
into the mounting bracket. Terminate the conductor. See Notes (page 2) for
currents under 1 Amp or above 135 Amps.
3. Wire the output connections to the DDC controller or switched load (solid state
contact).
4. Secure enclosure and reconnect power.
5. Calibrate the sensor (see Calibration section).
