Performing a re-
set after a rapid
shutdown To restart the PV system after a rapid shutdown:
- If the signal line to the inverter is closed, there must be an AC connection
present to restart the PV system.
- Open the switch that was used to trigger the rapid shutdown
- Check all other external switches in the signal loop to see if they are closed.
Self-test A self-test of the rapid shutdown function (RSD) can only be performed manu-
ally. The self-test only affects the discharge circuit of the Rapid Shutdown Box.
Manual self-test sequence:
A manual self-test can be triggered by an interruption of the AC connection (e.g.:
AC breaker).
The discharge of the Rapid Shutdown Box must be measured and checked using
a multimeter.
The Error-Code “AC_SystemFailure” is shown on the display of the inverter.
