Serial Communication connection (RS485)
The inverter has two RS485 communication lines with the communication
protocol which can be set in "Aurora" (proprietary communication protocol)
or ModBus (public communication protocol). The default conguration
of the protocol for both communication ports is "Aurora" which can be
changed through the advanced "Aurora Manager LITE"conguration
software.
Both RS485 lines can be used to:
- connecting the inverter to monitoring devices
- carry out conguration operations using the “Aurora Manager LITE”
conguration software.
- sending power management commands
The two lines only differ in terms of the rmware upgrading (locally or
remotely through the ABB monitoring devices) which must be carried out
by connecting to the RS485 (1) port
When connecting the ABB monitoring devices, the RS485(1) line must
be used
Cables connecting the RS485 line may use two different types of
connection:
• Connection of the conductors using the terminal connectors a11
(+T/R, -T/R, RTN e SH)
The SH connection must be used for connecting the
shielding boot(s) of the cable(s).
• Connection of conductors with RJ45 connectors a14 or a16
The two RJ45 connectors (A) and (B) available for the RS485
communication, are equivalent to each other and can be used
interchangeably for the arrival or for the output of the line in realising the
daisy chain connection of the inverters.
