2. If no further inverter connected, terminate the inverter:
On the sockets "RS485 OUT" with REFUSOL round plugs bypass the connections PIN1 to PIN2 and PIN3 to
PIN4.
3. Close the inverter if no other inverters are to be connected.
4. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connect the inverters to each other
•
Connect using
– 2-wire, shielded data cable and
– 4-pin "SACC-M12MS-4SC" plug (two plugs included with the inverter)
•
Where to connect: RS485 sockets on the bottom of the inverter.
The RS485 IN and OUT sockets are each double connections so that the wiring can be continued to the next inver-
ter.
Procedure
1. Connect the data cable to the "SACC-M12MS-4SC" plug as shown in the inverter's instructions.
2. Insert one plug into the OUT (X14B) socket of inverter 1.
3. Insert the other end of the wire into the IN socket (X15B) on inverter 2.
4. Connect the other inverters to each other in the same way.
5. Terminate the last inverter.
On the sockets "RS485 OUT" with REFUSOL round plugs bypass the connections PIN1 to PIN2 and PIN3 to
PIN4.
6. Close inverters.

[x = continuous numbering starting with 1; highest possible address: 31], press "ENTER". 31], press "ENTER".
After configuring on the display:
1. Using the installed DC isolating switch turn the inverters on and off briefly so that the settings are activated.
2. Set the date and time on the inverter as shown in the inverter instructions.
Older Solar-Log™ / Refusol installations: Set compatibility
With older Solar-Log™ / Refusol installations the inverter had to be set with additional parameters for Solar-Log™
compatibility. This is only still necessary if an inverter has been replaced because it was faulty
