Grid failure phase-to-phase
voltage
Error message indicates that the phase/phase
voltages are outside the permissible limits.
(Limit values are country-specific.) A significant
increase in voltage in the plant can be brought
about by an overly small cable cross-section.
Measure the
voltages on the
device terminal and
compare to the rel-
evant country-spe-
cific limit. Check set-
ting values in the
parameters menu.
Check the AC fuses:
A phase may be
missing.
Check connection/
cabling!
B/K
48
Grid failure underfrequency Measured value for grid frequency is outside
the permissible limit. Limit is country-depend-
ent. Grid frequency below the minimum per-
missible grid frequency set
Question: Which
country is set? Are
all 3 AC voltages
present? Check set-
ting values in the
parameters menu.
Check connection/
cabling!

49
Grid failure overfrequency
Measured value for grid frequency is below
the permitted limit. This limit is country-spe-
cific.
See action in the
event of a fault 48
E
50
Grid failure average voltage The grid voltage measurement according to EN
50160 has exceeded the maximum permitted
limit value. This fault may be grid-related.
This is a require-
ment of the relev-
ant norm. Check
setting values in the
parameters menu.

If there is an error in
one of the 4 soft-
ware specifications,
this indicates that
the software has
not been correctly
unzipped. Due to
feed-in, the AC
voltage on the in-
verter terminals is
raised. The voltage
measured by the in-
verter is dependent
on the amount of
grid voltage and the
cross-section of the
cabling.

Waiting for reconnect
Waiting time of the device following an error. The devices
switches on after a
country-specific
waiting period.
