Connecting The Wires To The Terminals; Connecting The Rapid Shutdown Box To An Inverter - Fronius DUO Instrucciones De Instalación

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 can-
not be used for further functions (Energy Manager, alarm, etc.), if the Rapid Shutdown
is to be initialized by means of an AC failure.
The inverter doesn't have to be configured after the installation of the Rapid Shutdown Box.
If changes were made in the section energy management, check this section in the invert-
ers user manual. The energy manager (Relay Mode) must be set ‚ON' (default value).
