fan signal line to main line, between junction boxes and signal connector from
inverter you must use same wire RS485 used for signal line.
For connection and wire colour, you have to follow electric diagram.
Warnings for maintenance and diagnostic actions

done by remote connection.

connect to it.
Therefore, DURING THE INSTALLATION IT IS MANDATORY:
Pull always the A and B wires down to the switchboard (to connect with 1)
the fan)
Set down in a scheme the Serial Number and the Modbus Address of each 2)
motor, as well as their placement (to univocally identify each single ma-
chine) in case of maintenance
Verify that in the same line there are not in- 3)
stalled two motors with identical Modbus Ad-
