Appendix A: How to connect the laptop PC to the inverter
To use the Aurora Manager LITE software, connect the laptop PC to the inverter on the RS485 PC/SERV port of the
communication board using an USB-RS485 Adapter (the ABB PVI-USB-RS232_485 Converter is recommended). The following
steps must be performed:
−
Switch OFF the inverter using the DC disconnect
−
Remove the wiring box cover by unscrewing the six (6) lateral screws
−
Remove the mylar cover on the communication board
−
Connect the RS485 cables on the PC/SERV port (see top blue rectangle box in Figure 6 above) using an RJ45 plug, or the
terminal block (see bottom blue rectangle box in Figure 6 above) by wiring the GND COM, PC +T/R and PC –T/R as shown in
Figure 7 below.
