Overview
 Interface integrated
 2 pin wiring
 Communication address must be allocated.
 Work steps
• Switch off the inverters and the SolarLog™;  Page 17
• Connect inverters to the Solar-Log™
• Connect the inverters to each other
• Allocate communication address
Connecting inverters to the Solar-Log™
The wiring is done using the
 ready-made data cable (optional extra; not supplied)
or
 self-made, shielded 2 wire data cable and terminal block connector
( Page 15).
Procedure
1 If you are fabricating the cable yourself, connect the wires as shown in the
following diagram:

 3 (B in)
2 If only one inverter is to be connected it must be terminated:
Insert 120 Ω terminal resistor.
3 Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connecting the inverters to each other (Solar-Log

)
 Connect using a 2 wire, shielded data cable.
 Where to connect: Terminal strip inside the inverter
Procedure
1 Connect terminal 2 (A out) on inverter 1 to terminal 4 (A in) on inverter 2.
2 Connect terminal 1 (B out) on inverter 1 to terminal 3 (B in) on inverter 2.
3 Connect the other inverters to each other in the same way.
4 Terminate in the last inverter: Insert 120 Ω terminal resistor.
