5 - Installation
For both type of connection, proceed to connect all the units of the RS485
chain in accordance with the daisy-chain model observing the correspon-
dence between the signals, and activate the termination resistance of the
communication line in the final element of the chain by switching:
- the
54
switch for the RS485-1 line in the ON position.
- the
58
switch for the RS485-2 line in the ON position.

The communication line must also be terminated on the first element of the chain which nor
-
mally corresponds to the monitoring device.
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.
When connecting a single inverter to the monitoring system, activate the
communication line resistance terminal by setting the switch
54
or
58
(to
the ON position).
Set a different RS485 address on each inverter in the chain.
No inver-
ter 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 "Aurora
Manager" software.
When an RS-485 connection is being used, if one or more inverters are
added to the system at a later time, it is necessary to remember to reset
to OFF the switch on 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
54
or
58
in the OFF position.
