3.2.5 Configuring the Fallback
If the communication between the inverter and the SMA
Inverter Manager is interrupted, the inverter switches to a
previously defined operating state (Fallback). The desired
operating state when communication is interrupted, can be
activated and configured with the customer-specific grid
code file or via the LCS tool. For further information on the
configuration of the system fallback between the SMA
Inverter Manager and a superior control unit (e.g. SCADA
system or Power Plant Controller) see installation manual of
the SMA Inverter Manager / SMA Digital I/O Box / LCS
Tool.
