7 Troubleshooting
Error no. Explanation
0404* Frequency change per second too
high for grid operation
0502* Power frequency is too low. Power
frequency disturbance detected by
standard monitoring.
0503* Power frequency is too high.
Power frequency disturbance de-
tected by standard monitoring.
0504* Power frequency is too low. Power
frequency disturbance detected by
redundant monitoring.
0505* Power frequency is too high.
Power frequency disturbance de-
tected by redundant monitoring.
0506* The inverter has detected a stand-
alone grid and has disconnected
from the utility grid.
0801* One line conductor of the utility
grid has failed.
0802*
1301 Left-hand rotating magnetic field is
connected.
1500 The conditions for grid reconnec-
tion have not yet been reached af-
ter a grid error.
* Depending on the parameterization, the disturbance message may have to be acknowledged manually.
