7.4 Wireless network
It is possible to connect the EV chargers between themselves and to the backend through wireless connection.
The connection between EV chargers is facilitated by a Wi-Fi router and the connection to the backend is done through
Wi-Fi or 4G.
If an energy meter is used, it needs to be connected either to the Master or to the Wi-Fi router with an RJ45 cable.
If the energy meter is connected to the Master with an ethernet cable, it is recommended to configure the EV charger
nearest to the energy meter as Master to limit the length of the ethernet cable.
