(PVI-STRINGCOMB (-S, -MC, -S-MC) - Rev:1.0)
7 CONNECTION OF THE RS485 LINE
The connection for communications sent out from the PVI-STRINGCOMB(-S)
uses the RS485 serial line.
The type of connection between the Aurora inverter and the PVI-
STRINGCOMB(-S) must be made as indicated in Figure 7-1 and Figure 7-2.
Termination of the line is already provided for inside the inverter (120
ohm).
The last PVI-STRINGCOMB(-S) must be terminated with 120ohm. This
operation is explained in §9.3.2.
Use of a computer is not a key to system operation. But it is necessary
in order to assign the FIELD NUMBER upon installation (Ref.§9.3.20,
§12.4.2)
