Check other DATCOM components for errors in order to identify an existing undervolt-
age.
After a shutdown due to overcurrent or undervoltage, the inverter tries to restore the energy
supply in the Fronius Solar Net every 5 seconds so long as there is an error, for example.
Once the error has been corrected, power is restored to Fronius Solar Net within 5 sec-
onds.
Example
Logging and archiving inverter and sensor data using a Fronius Datamanager and Fronius
Sensor Box:
Data network with three inverters and one Fronius Sensor Box:
- inverter 1 with Fronius Datamanager
- inverter 2 and 3 without Fronius Datamanager
External communication (Fronius Solar Net) takes place in the inverter via the data com-
munication area. The data communication area has two RS-422 interfaces: an input and
an output. RJ45 plug connectors are used to establish the connection.
IMPORTANT!
Only one master Fronius Datamanager is permitted per Fronius Solar Net
Ring. Additional Fronius Datamanager slaves can be switched or removed (see section en-
titled "Controls and Indicators on Fronius Datamanager 2.0" on page 16).
Unused option card slots can be closed by replacing the cover (item number
42,0405,2094), or an inverter without Fronius Datamanager (light version) can be used.
