Overview
•
Integrated interface (two independent RS485 ports) (see Figure: Gefran RS485 terminal strip and termination).
•
Where to connect: Terminal strip inside the inverter.
•
2-pin wiring.
•
Communication address has to be assigned.
•
Installation steps:
•
Switch off the inverters and the Solar-Log™.
•
Connect inverters to the Solar-Log™.
•
Connect the inverters to each other.
•
Allocate communication address.
Connect inverters to the Solar-Log™
The wiring is done using a
•
self-made, shielded 2-wire data cable.
Note
The two independent RS485 ports allow for different ways to wire the Solar-Log™ to the inverters. In
addition there are different pin assignments based on whether port A or B is used.
Procedure
1. Open the inverter as shown in the inverter’s instructions.
2. If you are making the cable yourself, connect the wires as shown in the following diagram:

Terminal strip RS485 (TB3)
►
1 A/Data+
►
Pin 1 or 2 (Port A) or Pin 9 or 10 (Port B)
►
4 B/Data-
►
Pin 3 or 4 (Port A) or Pin 11 or 12 (Port B)
3. If no further inverter connected, terminate the inverter:
Set the switch (switch S1 for port A, switch S3 for port B) in the inverter to “1” for terminal resistance.
4. Close the inverter.
5. Insert the terminal block connector into the Solar-Log™ RS485 socket.
