Refer to the figure shown below, connect the RS485+ and RS485- of the inverter to
the TX+ and TX- of the RS485
→
USB adapter, and connect the COM port of the
adapter to the computer. (NOTE
：
The length of the RS485 communication cable
should be less than 1000 m)
Connect pins as shown(2pin and 3pin)
Figure 4.4.5-3 RS 485 wiring diagram
RS485 wires are connected in parallel between inverters, (NOTE
：
When multiple
inverters are connected via RS485 wires, set communication address to differentiate
the inverters

, also known as inverter demand
response modes (DRMs).
The inverter will detect and initiate a response to all supported demand response
commands within 2 s. The inverter will continue to respond while the mode
remains asserted.
