5.4.2. Connecting the Meter
Due to the stability of the RS485 signal, for distances greater than 50 metres between the inverter
and measuring point, it is necessary to use the Meter in addition to the sensors, as shown in the
figure.
Make sure to position the probes so that each toroid reads only the current flows relating to the
exchange. To do this, it is recommended to position them at the output of the exchange meter.

This involves connecting the sensors to the Meter, and then connecting the Meter to the inverter
via a serial port.
