Serial communication connection (RS485 - Master mode)
The RS485 port can either be used for connecting supported accessories (like weather station): in
this case data from accessories will be logged and transferred to the cloud by inverter itself (master
mode).
This will allow the inverter to serve as a logger for FIMER accessories.
NOTE – D For more information on connecting the accessories to the RS485 terminal block,
refer to the accessory product manual or contact FIMER customer support.
• Connection of the R485 communication line is made
using the terminal block connectors (43) (485+, 485-,
RTN and SHIELD).
• Set the switch of the termination resistance (40) to“ON”
position.
• When an accessory is connected it must be added and
configured into the “Monitored device” list on the Web
User Interface (“CONNECTIVITY > RS485” refer to
“CONNECTIVITY menu” paragraph to further
information).
Remote control connection
The connection and disconnection of the inverter from the grid can be controlled through an external
control by enabling the Remote ON/OFF function on the relevant section of web user interface
(“SETTINGS > INVERTER PARAMETERS > DIGITAL INPUTS”, refer to “SETTINGS menu”
paragraph).
If the remote control function is disabled, the switching on of the inverter is dictated by the presence
of the normal parameters that allow the inverter to connect to the grid.
When the functionality is active the switching on of the
inverter, besides being dictated by the presence of the
normal parameters that allow the inverter to connect to the
grid, also depends on the state of the R2 terminal
compared to the RTN terminal present on the terminal
block (42) of the communication and control board (26).
When the R2 signal is brought to the same potential as the
RTN signal (i.e. by making a short circuit between the two
terminals of the connector), this causes the inverter to
disconnect from the grid.
Since this is a digital input, there are no requirements to
be observed as regards cable cross-section (it only needs
to comply with the sizing requirement for passing cables
through the cable glands and the terminal connector).
The external switch used for Remote ON/OFF should be rated for DC low voltage, low current
application (the minimum switching current capability should be 1mA or lower).
