Article 01455 is used to manage both the consumption and production of the energy system or is it also necessary to install article 01450?

Article 01455 is designed for the inlet of three current sensors. This means that in a single phase system in which the production meter is at a maximum distance of 40 cm from the consumption meter, it is possible to use only art.01455 with two current sensors.
In three-phase systems or single phase systems with a production meter located in another room or at a distance of more than 40 cm, in addition to the load control module art.01455, you will also need meter art.01450.
