Installation & Wiring

Installation involves mounting a bracket, connecting power cables to the terminal block, and securing the sensor. Major Tech advises avoiding reflective surfaces, heat sources, and objects that move in the wind for optimal performance. Wiring must be performed by a qualified electrician, ensuring the power source is disconnected and live components are shielded.
