Connect the inverters to each other
•
Connect using a 2 wire, shielded data cable
•
Where to connect: Terminal strip inside the inverter
The RS485 connections on the terminal strip are each double connections so that the wiring can be continued to
the next inverter.
Procedure
1. Open the inverter as shown in the inverter's instructions.
2. Connect terminal A on inverter 1 to terminal A on inverter 2.
3. Connect the other inverters to each other in the same way.
4. Terminate the last 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 inverters.
Allocate communication address
•
Recommendation: Continuous numbering starting with 1.
•
Setting:
Units without transformers: using the DIP switch inside the inverter
Units with transformers: using the inverter operating display.
•
Procedure: Start according to the inverter's instructions
Note
A maximum of 32 inverters can be connected per RS485 bus.
