6.10 Electric arc hazards
6.10.1 Arc-Fault Circuit Interrupter(AFCI)
In accordance with the National Electrical Code R, Article 690.11, the inverter
has asystem for the recognition of electric arc detection and interruption. An electric
arc with a power of 300 W or greater must be interrupted by the AFCI within the time
specified by UL 1699B. A tripped AFCI can only be reset manually. You can
deactivate the automatic arc fault detection and interruption (AFCI) via a
communication product in "Installer" mode if you do not require the function. The
2011 edition of the National Electrical Code R, Section 690.11 stipulates that newly
installed PV systems attached to a building must be fitted with a means of detecting
and disconnecting serial electric arcs (AFCI) on the PV side.
