Note::::
(1) When using analog input, you can connect filter capacitor or
common mode inductor between VI and GND, or CI and
GND.
(2) Because analog input signal is easily interfered by outside, the shield cable is required, the cable length must be short
and the shield layer must be grounded well.

The communication port of this inverter is standard RS485 port.
With the following wiring methods, you can buildup control system of one host with one slave or one host with several
slaves. Also, you can realize the functions such as real time monitor, remote control, high level automation and others for
the inveter with the host (PC or PLC) software.

More than one inverters can be connected through RS485 with the PLC(or PC) as the host, as shown in Fig.2-10; Also,
you can select one inveter as host and the other inverters as slaves, as shown in Fig.2-11.Because with increasing of the
inverter’s quantities, the communication system will be interfered easier, the following wiring is recommended.
