Abstract

A control installation includes a DC power supply (4) able to power a plurality of electrical units (3), and a system (5) for managing the power supply to the electrical units (3). The installation also includes a transmitter control device (1) including radiofrequency transmission elements (10) and actuators (11) each including a transducer making it possible to control the transmission of a radiofrequency signal, and a receiver control device (2) making it possible to send to the management system (5), control signals, dependent on the radiofrequency signal or signals received, so as to activate or deactivate the power supply to at least one part of the electrical units (3). The invention also relates to a structure and a corresponding method of mounting.
