Island detection Immediate grid disconnection when island operation
detected (Anti-Islanding)
Inactive/
on
Monit. ext. input The status signalling contact is congured for monitor-
ing an external input.
Inactive/
on
Restart delay Delay time before grid reconnection upon previous
failure-related grid disconnection.
s
Pac progression Maximum increase of the effective power during grid
reconnection upon previous failure-related grid discon-
nection.
%/min
Soft Start Maximum increase of the effective power at grid con-
nection. This gradient, if activated, is always effective,
as opposed to “Pac Progression” (even during restart
in the morning).
W/s
Mains check Additional mains check before connecting to the grid Inactive/
