Disconnect and lock-out all power sources during installation
Mount sensor in a convenient location, within or adjacent to the breaker panel.
Alternatively, the sensor can be installed inside the dryer electrical compartment.
(3-Phase systems) Disconnect and loop the neutral power wire, WHITE, through the current sensor and reconnect
(220V AC 3-wire single-phase systems) Determine which of the Hot wires is active for the dryer only.
Verify that there is sufficient current to trip the current switch (minimum of 1 amp).
If required the wire can be looped through twice to increase the current read by the switch.
Connect the fan power supply, 120V AC Max, to the top terminals of the current sensor
