3.9.4 RS485 termination
Terminate the data connection at its beginning and at its end to ensure faultless data trans-
mission:
•
Beginning of the data connection: terminate external data logger in accordance with the
manufacturer's instructions.
•
End of the data connection: insert termination plug into the vacant RS485 interface of
the last inverter.
3.9.5 RS485 addressing
All inverters are set to address "1" at the factory. For the master-slave communication,
each inverter requires its own address. The address is changed in the menu under "Set-
tings" > "RS485 address".
•
If possible, assign the addresses starting with 1 at the first inverter and ascending to the
last, as the number of possible addresses in the inverters is limited.
•
The sequence of addresses should mirror the order of the mounted devices, to facilitate
the identification of the devices.
3.9.6 Connecting an energy meter (Modbus RTU)
The inverter is able to communicate with energy meters via the "COM2" connection. To do
this, the energy meter must meet the following requirements:
•
The energy meter has been preprogrammed in the inverter.
•
The energy meter measures the draw from the grid in positive direction (refer to instruc-
tions of the energy meter).
Modbus RTU data connecting cable
NOTE
Voltage may cause property damage.
►
Only have specialists manufacture the alternative data connecting cable.
Use a RJ45 standard cable or a CAT5 patch cable as data connecting cable.
