Fcc / Rss Compliance; Device Concept - Fronius Rapid Shutdown Box - Duo Instructions De Service

IMPORTANT! The system status indicator (inverter) shall be installed in a location in close
proximity to the system initiator, where the indication of safe shutdown can be clearly seen.
If the rapid shutdown initiation is loss of AC, the inverter acts as system initiator and indi-
cator.

Device concept

The Rapid Shutdown Box provides a convenient and safe way to comply with Article
690.12 in the 2014 Edition of the National Electrical Code. The device is powered directly
by the PV array and is controlled depending on the state of the signal port. This signal port
can be controlled by a relay terminal in the inverter. The use of a DC relay, which also func-
tions as a switch-disconnector, ensures that the PV array is galvanically isolated in the
case of a Rapid Shutdown.
The Rapid Shutdown Box ensures that residual energy in the capacitors of the inverter is
discharged within the required time period. To ensure that the entire system functions cor-
rectly, the signal ports of all Rapid Shutdown Boxes must be serially connected (see sec-
tion "Connecting the Rapid Shutdown Box"). For this purpose, Duo and Quattro variants of
the device can be mixed randomly.
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.

NOTE! When installing outdoors, only use waterproof conduit fittings and con-
duits. Conduit fittings and conduits are not included in the Rapid Shutdown Box's
scope of supply. Conduit fittings must always be installed with a locking nut. En-
sure that the conduit fittings are installed and sealed correctly.
NOTE! When connecting DC cables, ensure the polarity is correct.
FCC
This device corresponds to the limit values for a digital device of class B in
accordance with Part 15 of the FCC regulations. The limit values should pro-
vide adequate protection against harmful interference in homes. This device
creates and uses high frequency energy and can interfere with radio com-
munications when not used in accordance with the instructions. However,
there is no guarantee against interference occurring in a particular installa-
tion.
If this device interferes with radio or television reception when turning the de-
vice on and off, it is recommended that the user solve this with one or more
of the following measures:
- adjust or reposition the receiving antenna
- increase the distance between the device and the receiver
- connect the device to another circuit, which does not include the receiv-
er
- for further support, please contact the retailer or an experienced radio/
TV technician.
