Creating an RS485 Bus Connection
4. Loosen the screws of pins A(+), B(-), and G on the left of the RS485 terminal block (RS485-1 or RS485-2).
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.
6. For creating an RS485 bus - connect all B, A and G pins in all inverters. The following figure shows this
connection schema:
NOTE
Do not cross-connect B, A and G wires.
7. Tighten the terminal block screws.
8. Check that the wires are fully inserted and cannot be pulled out easily.
9. Push the RS485 terminal block firmly all the way into the connector on the right side of the
communication board.
