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 volt-
ages on the device
terminal and com-
pare to the relevant
country-specific
limit. Check setting
values in the param-
eters menu. Check
the AC fuses: A
phase may be miss-
ing.
Check connection/
cabling!

48
Grid failure underfrequency Measured value for grid frequency is outside
the permissible limit. Limit is country-depen-
dent. 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.
