  • Page 17 Provide a protected under load disconnector (circuit breaker or fuses) with appropriate disconnection power and capacity according to the absorption characteristics of the equipment model. Use cables of an appropriate size with respect to the rated absorbed current. Earth connection must be performed according to the applicable laws. Special care must be applied to the earth connection of the antenna system since it is exposed to electrical atmospheric events.

  • Page 18: Exposure Evaluation

    2.4 Exposure evaluation Exposure assessment requires the identification of electric field values in places where the presence of people may occur. The field values must refer to the type of stay and the exposed subjects, according to the provisions of current legislation. The identification of the electric field values can be carried out in various ways, depen ding on the need for precision and the fact that one intends to perform a prediction, or a subsequent verification.
