The communication line must also be terminated on the first element of the chain which

normally corresponds to the monitoring device.
ON OFF
It is recommended not to exceed a length of 1000m for the communication line.
The maximum number of inverters that can be connected to the same RS485 line is 62.
In case of longher communication line and/or in case of a large number of connected inverters
X2
to the same line it could be necessary to add a RS485 amplifier to guarantee the performance
of the communication line.

Connect all the units of the RS485 chain in accordance with the daisy-
chain model observing the correspondence between the signals, and
activate the termination resistance of the communication line in the final

Set a different RS485 address on each inverter in the chain. No inverter
can have "Auto" as an address. An address can be freely chosen
between 2 and 63.
The setting of the address on the inverter is done through the integrated
Web User Interface (refer to chapter "Web User Interface").
X1
When an RS-485 connection is being used, if one or more inverters are
X1
added to the system at a later time, it is necessary to remember to reset
to OFF the switch of the termination resistance being used (1) or (2) on
the inverter which previously was the last in the system.
Each inverter is shipped with the RS485 address pre-set to two (2) and
with the resistance terminal setting Switch
