Overview
•
Interface integrated
Sometimes different interfaces are used for indoor and outdoor models.
•
Where to connect: RS485 terminal strips inside the inverter
•
3-pin wiring
•
Communication address must be allocated.
•
Installation steps
• Switch off the inverters and 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
•
ready-made Power One data cable (optional extra; not supplied)
or
•
self-made, shielded 3 wire data cable and terminal block connector.
Procedure
1. Open the inverter as shown in the inverter's instructions.
2. Pull the free wires through the wire opening in the inverter.
3. If you are making the cable yourself, connect the wires as shown in the following diagram:
Solar-Log™ terminal strip connector Inverter terminal strip (Outdoor)
Terminal Terminal
► 1 ► +T/R (PC)
► 3 ► GND
► 4 ► -T/R (PC)
4. If only one inverter is to be connected this must be terminated.
In the inverter, set the DIP switch for the terminal resistor to ON.
5. Close the inverter if no other inverters are to be connected.
6. Insert the terminal block connector into the Solar-Log™ RS485 socket.
