System Limitations; Maximum Distance Between The Rapid Shutdown Box And The Pv Array; Technical Data - Fronius DUO Instrucciones De Instalación

The Rapid Shutdown can be initialized by means of AC failure if the signal lines are con-
nected to the inverter. Alternatively or additionally, an emergency stop button that inter-
rupts the signal wires can be used.
