CODE COMPLIANCE FRONIUS RAPID SHUTDOWN BOX
Fronius International GmbH
hereby confirms that the Fronius Rapid shutdown devices
/ Fronius Rapid Shutdown Box - Single
/ Fronius Rapid Shutdown Box - Multi
comply with Article 690.12 in the 2014 Edition of the National Electrical Code.
The devices are powered directly by the PV array and are controlled by low voltage signal wires connected at a
separate terminal of the output terminal block of the RSB device. The signal wiring is controlled by a relay terminal
in the inverter and activated by loss of AC power. The use of a DC relay ensures that the PV modules are
galvanically isolated from the inverter in the case of a Rapid Shutdown.
After triggering the rapid shutdown process, the Fronius Rapid Shutdown Box devices together with the following
Fronius inverters will cause the voltage of the PV homerun conductors to the inverter to decrease to less than
30V in under 10sec, as required in Article 690.12, NEC. Following Fronius inverter are compatible with the Fronius
