Don't connect GND to port 7 of the Gavazzi meter

If you have a SUN2000L inverter and you bought an energy meter Carlo Gavazzi EM111DINAV81XS1X08 do not install the GND on the port 7 of the meter.

WHY?

1. It may cause an abnormal communication with the inverter.

2. It may work abnormally sending incorrect data to the monitoring portal.

3. If you set the Zero export to the grid mode, when you want to choose this option the inverter may block and both LEDs become RED.
