was activated by the grid operator.
The inverter limits its power.

Measured values
P(f )/frequency-dependent power reduction: Frequency-depend-
ent power reduction will be activated when the BDEW (German
Association of Energy and Water Industries) Medium Voltage
Directive goes into effect. Power reduction starts at a frequency of
50.2 Hz.
OS

Measured values
Output current limiting: The AC current is limited once the speci-
fied maximum value has been reached.

Overvoltage has been detected on
a conductor. An internal protec-
tive mechanism has disconnected
the device to protect it against
damage.

Protection shutdown
undervolt. DC link
A voltage deviation has been
found in the DC link. An internal
protective mechanism has dis-
connected the device to protect it
against damage. In a TN-C-S grid,
the PE must be connected to the
device and at the same time the
PEN bridge in the inverter must be
removed.
