6.9 AFCI(Optional)
6.9.1 Arc-Fault Circuit Interrupter (AFCI)
In accordance with the National Electrical Code R, Article 690.11, the inverter has a
system 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.
6.9.2 Danger information
Danger of fire from electric arc
Only test the AFCI for false tripping in the order described below.
Do not deactivate the AFCI permanently.
If an "Error 200" message is displayed, the buzzer alarms, an electric arc occurred in
the PV system. The AFCI has tripped and the inverter is in permanent shutdown.
