Connecting the Connection to the Inverter:
Rapid Shutdown If the AC supply to the inverter is interrupted, the inverter disconnects the PV DC supply
Box to an Inverter via the Rapid Shutdown Box. As soon as the AC supply is reinstated, the DC supply will
resume.
The signal relay in the Fronius inverter is designed to open when the inverter loses AC
power signaling the Rapid Shutdown Box to disconnect. However, the signal relay cannot
be used for further functions (Energy Manager, alarm, etc.), if the Rapid Shutdown is to be
initialized by means of an AC failure.
