Grid failure underfrequency Grid frequency below the minimum permiss-
ible grid frequency set
Check set values in
the parameter
menu. Fault can be
caused by a poor
connection on the
AC side. Check con-
nection terminals
from the device to
the grid connection.

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.
