Connect inverters to the Solar-Log™
The wiring is done using a
•
ready-made data cable (optional extra; not supplied)
or
•
self-made, shielded 2 wire data cable and terminal block connector.
Procedure
1. If you are making the cable yourself, connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector Inverter terminal strip
Terminal Terminal
► 1 ► 4 (A in)
► 4 ► 3 (B in)
2. If only one inverter is to be connected this must be terminated.
Insert 120 Ω terminal resistor.
3. Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connect the inverters to each other
