81
Protection shutdown grid
voltage L1
Overvoltage has been detected on a con-
ductor. An internal protective mechanism has
disconnected the device to protect it against
damage.
Poll the wiring on
the AC side (e.g.
voltage spike due to
inductance of a
transformer). If the
fault message ap-
pears frequently or
always, the installa-
tion must be
checked. If there is
nothing wrong with
the installation,
then there is a fault
in the device. This
error can be caused
by a poor connec-
tion/cabling on the
AC side. Check all
connection termin-
als from the in-
verter through to
the grid connection.
Fluctuating AC
voltage can trigger
this fault.

Protection shutdown DC link
undervoltage
If the min. value of the DC link voltage is not
reached, this will be displayed. If the device
stops feeding in, then there is a fault. Other-
wise, a highly inductive grid is responsible for
this.
Poll the wiring on
the AC side (induct-
ance of a trans-
former). This error
can be caused by a
poor connection/
cabling on the AC
side. Check all con-
nection terminals
from the inverter to
the grid connection.
Fluctuating AC
voltage or a lack of
AC voltage may in-
dicate that this
problem exists.

overvoltage
If the max. value of the DC link voltage is ex-
ceeded, this will be displayed. If the device
stops feeding in, then there is a fault

86
Protect. shutdown unbal. DC
link
Overvoltage has been found in the DC link. An
internal protective mechanism has disconnec-
ted the device to protect it against damage.

87
Protection shutdown over-
current L1
A current that has been found on a conductor
is too high. An internal protective mechanism
has disconnected the device to protect it
against damage.
Poll the wiring on
the AC side (induct-
ance of a trans-
former).
