Overview
•
VPI until 2005 RS485 interface can be retrofitted by the manufacturer.
•
Interface integrated - activate using operating display.
•
Where to connect: Terminal strip inside the inverter
•
2-pin wiring
•
Communication address must be allocated.
•
Installation steps
•
Switch off the inverters and Solar-Log™
•
Models until 2005 Retrofit RS485 interface
•
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 data cable (optional extra; not supplied)
or
•
self-made, shielded 2 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:

4. If no further inverter connected, terminate the inverter:
In the inverter connect the free terminal A to terminal B using the supplied 330
Ω
terminating resistor.
Devices without a transformer: From unit generation VPI xx00 /2 the 330
Ω
resistor is switched on using the
DIP switch. When the unit is delivered the terminal resistor is switched 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.
