Status codes –
Class 7 Class 7 status codes relate to the control system, the configuration and inverter data re-
cording, and may directly or indirectly affect the process of feeding energy into the grid.
573 Undertemperature warning Warning message on
the display
*)
581 "Special Purpose Utility-Inter-
active" (SPUI) setup activated The inverter is no longer
compliant with the
IEEE1547 and
IEEE1574.1 standards
because the standalone
function has been deac-
tivated, a frequency-de-
pendent power
reduction has been acti-
vated and the frequency
and voltage limits are
being changed
No error
