<p>The device (1) has a switching module (SW) comprising an input (I1) connected to a power supply unit (PWR) and another input (I2) adapted to be connected to an electric source (ELEC) external to the device. An output (S) of the switching module is adapted to be connected to an electric meter (COMPT). The switching module connects the former input with the output in a functioning state after receiving a resupply request by the device.</p> |
