Message, cause and corrective measures
1413
Grid incident
Phase position of the measured AC voltage at
ExtVtg
and
AC2
does not match at line con-
ductor Lxx.
Corrective measures:
• Ensure that the neutral conductor and line conductor are correctly connected to
connection
ExtVtg
.
• Ensure that the neutral conductor and line conductor are correctly connected to
connection
AC2
.
• Ensure that connections
ExtVtg
and
AC2
are connected to the same line conductor.
1415
Grid incident
Tie switch does not close.
Corrective measures:
• Ensure that the triggering of the tie switch is correct.
• Ensure that the tie switch is correctly wired.
• Ensure that the feedback contact is correctly connected.
1416
Grid incident
The Sunny Island system disconnects from the generator or utility grid due to a power imbal-
ance between the line conductors.
Corrective measures:
• Eliminate any faults in the installation.
