When more than 15 inverters are connected on the same daisy chain, the inverters on
two ends of the chain should be equipped with terminal resistors of 120Ω to ensure
communication quality by configuring the dip switch (SW1), and the shielding layer of
the communication cable should be single-point grounded.

The length of the RS485 cable and twisted pair cable should be no longer than
1,200m.
If multiple inverters are connected to the data logger, the number of
permissible daisy chains and the number of devices allowed to be connected
should meet the requirements (refer to the user manual for the data logger).
