5. Insert the wire ends into the G, A and B pins shown above. Use Four- or six-wire
twisted pair cable for this connection.
You can use any color wire for each of the A, B and G connections, as long as:
The same color wire is used for all A pins the same color for all B pins and the
same color for all G pins
The wire for G is not from the same twisted pair as A or B.
6. For creating an RS485 bus - connect all B, A and G pins in all inverters. The following
figure shows this connection schema:
