Mount the concentrator board junction box within close proximity of the motor.
Route the flyleads from the motor bearing and sled sensors to this enclosure.
Mount it in a location that allows for easy accessibility and maintenance.
Each concentrator board supports up to 6 smart sensors. Sensor terminals 1-6 are clearly marked on the circuit board.
