7. RS485 Communication Interface
About RS485
A typical RS485 connection is as below.
Some Noteworthy Points:
1. Wires between devices and computer shall be twisted.
2. Maximum allowable wire length is 1000 meters.
3. The terminal-end device should have a terminal resistor.
4. Due to multiple connections, each individual device should be assigned an
IP address as to send/receive.

1. Connecting T/R1+ and T/R1- of inverter RS485 connector to the T/R+ and
T/R- of the data logger respectively.
2. Between two inverters, connecting T/R2+ of first inverter with T/R1+ of next
inverter, and connect T/R2- of first inverter with T/R1- of next inverter.
3. Set terminal resistor switch “ON” of the terminal-end inverter (the last
inverter of the row) only. The others should be set as “OFF”.
Setting the Terminal Resistor
Each inverter has built-in terminal resistor, if RS485 is connecting to multiple
inverters or the total communication length is too long to cause the abnormal
communication, please set the terminal resistor switch to “ON” of the last inverter
in the row connection, all other remaining inverters shall switch to “OFF”.

Attention!
Improper setting of the terminal resistor will cause
communication failure.
Use Standard RS485 Wire
In order to achieve good communication, be sure to use
standard copper mesh shielding of RS485 twisted. Do not use
general network cable as RS485 wire.
RS485 Cable AC and DC Cable Separately
To maintain good communication and reduce interference,
please separate the RS485 cables from the AC and DC wiring
and keep at least 10cm far away or use a cable with metal
shield isolation.

8. Troubleshooting
Please pay attention to the following matters by regularly visual check to ensure the
power limiter is operating normally.
1. Clean the dust on the power limiter.
2. Check the operation and status of the power limiter.
3. Check all wiring to confirm there is no corrosion or breakage.
4. Check all the terminals and make sure they are not loose.
Referring to below table to resolve accordingly. If the problem persists, please
contact your local service partners for further assistance.
Abnormal
Solution
LED no display
1. Check if the AC power is connected to the L1-N
position.
2. Switch off the AC power and switch on again.
LED in solid red color
1. Check if the direction of the CT buckle is on the
correct position.
2. Check if the CT +/- wiring is correct.
3. Check if the wiring of L1 / L2 / L3 voltage and
current are corresponding.
4. Check if the RS485 communication is operating
in normal (check if the green LED is flashing).
RS485 disconnection
1. Check the wiring and connector.
2. Check if the IP address of inverter is configured
correctly, and shall not duplicate the same IP
address of the other inverter.
3. Check if the last inverter in the row connection
is set terminal resistor switch “ON” , and all the
remaining inverters shall switch “OFF”.
If there is only one inverter, do not switch on
the terminal resistor.
4. Check if the cable is well twisted.
5. Keep the RS485 cable at least 10cm far away
from the AC and DC wires or use the cable with
metal shield isolation.
