Communication Connection
6.5.1 Communication Overview
The inverter operation information can be transferred via its integrated RS485
interface to a PC with monitoring software (such as Insight), or to data logging
device (such as Logger 3000).
RS485 is the standard communication choice for inverter.
The communication terminals (RS485) are located at the bottom of the inverter. And
the RS485 A/B terminal blocks are on the configuration circuit board.
If a 120
Ω
terminating resistor is to be connected between the communication cable
A and B, connect the terminal resistance by using the dip switch.

Before communication connection, prepare communication cable.
RS485 cable’s requirements to ensure quality of communication:
RS485 shielded twisted pair cables
Shielded network cable
Unscrew the packing nut of the Communication cable glands; poke
and remove the plastic plug inside the cable gland by screwdriver
before communication cable connection.
