Installation
Procedure
1 Open the inverter as described in the inverter instructions.
2 If you are fabricating the cable yourself, connect the wires as shown in the
following diagram:
Solar-Log™ terminal block connector
3 If only one inverter is to be connected it must be terminated:
Set the jumper on the RS485 interface card to ON.
4 Close the inverter if no other inverters are to be connected.
5 Insert the terminal block connector into the Solar-Log™ RS485 socket.
Connecting the inverters to each other (Solar-Log
500
, Solar-Log
1000
)
Connect using a 3 wire, shielded data cable.
Where to connect: Terminal strip inside the inverter (on the retrofitted
RS485 interface)
Procedure
1 Open the inverter as described in the inverter instructions.
2 Using the data cable connect terminals “Pin 2-RS485-A (+)”, “Pin 3-GND” and
“Pin 1-RS485-B (-)” of inverter 1 to the corresponding terminals on inverter 2.
3 Connect the other inverters to each other in the same way.
4 Terminate in the last inverter:
Set the jumper on the RS485 interface card to ON.
5 Close inverters.
Allocating communication address
Recommendation: Continuous numbering starting with 1.
Setting: Using the inverter operating display
Procedure: As set out in the inverter's instructions
