Note that the RS-485 signals (positive, negative and ground) of each inverter must share the same point or node.
For example, the negative signals (A-) of inverters 1, 2, 3 and 4 must be connected to the same node. The same
must be true for the positive (B+) and GND (if any) signals. It is important to remember that inverters in an RS-485
network must have different serial addresses.
5.2.2 ETHERNET
To connect to the WCD-ED300 via Ethernet GbE1 communication interface using the Modbus TCP protocol, it is
necessary to install on the CFW11 one of the accessories listed in
Table 5.4 . It is also important to observe the
following settings in the table:
