The RS485-1 crimp and the RJ45 interface can be applied to applications where multiple in-
verters communicate in a daisy-chain form.
A 120Ω resistor can be connected in parallel between RS485-1 A/B pins by configuring the
dip switch.
RS485-1 crimp interface and RJ45 interface serve as the same function with differ-
ent wiring manner.
5.10.2 RS485 Communication System
Single-inverter Communication System
In case of a single inverter, communication cable connection requires only one RS485 cable.
figure 5-4 Single-inverter Connection
Multi-inverter Communication System
In case of multiple inverters, all the inverters can be connected via RS485 cables in the
daisy chain manner.
