For correct RS485 wiring: Follow the guidelines for RS485 wiring.
If the wiring shown in the table below is incorrect, please let us know.
There is no general consensus in the industry about the usage of A and B for the RS485 polarity, so it may be counterintuitive and opposite of what you might expect for some devices.

Terminal 6 / B+	RS485 B	RS485_NEG	RS485 B	TX-

Kontroller, at Carlo Gavazzi måleren er sat til at aflæse både import og eksport effekt. En uhensigtsmæssig indstilling kan føre til:

Du kan sætte dette i ‘MEASurE’ konfigurationsmenuen på elmåleren. Denne bør være sat til ‘b’.

Denne indstilling kan muligvis ikke findes på MID-certificerede modeller (modelnumre der ender på PFA og PFB).

You MUST give each device on the RS485 bus a unique address. Check the manual of the device on how to do this.
Use lower addresses first (1, 2, ...) because the SmartgridOne Controller will find them faster!
For each device, it is generally recommended to stick with the factory default baud rate, parity, and stop bits. The SmartgridOne Controller will scan on those first.

Sæt Modbus-adressen gennem elmålerens “Address” konfigurationsmenu.
