•
When connecting a single inverter to the monitoring system,
activate the communication line resistance terminal by setting
the switch (40) (to the ON position).
• 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
Web User Interface (“CONNECTIVITY > RS485” refer to paragraph
“CONNECTIVITY menu”).
•
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 of the termination
resistance being used on the inverter which previously was the
last in the system.
NOTE – D Each inverter is shipped with the RS485 address pre-set to “2” and with the resistance
terminal setting Switch (40) in the OFF position.
