Derating The inverter reduces the output power due to high internal temperatures.
Corrective measures:
• Ensure that the inverter has sufficient ventilation.
• Ensure that air can emerge from the fan guards. If no air is emerging
from the fan guards, clean the fan guards (see Section 6.4).
dI-OCU
dI-Srr The inverter has detected a change in the differential current.
A change of the differential current can be caused by a ground fault,
residual current or a malfunction. The inverter disconnects from the power
distribution grid.
Corrective measures:
• Contact installer.
dI-Meas-Srr
dI-Meas The inverter has detected a deviation in the differential current
measurement. If this message is repeated frequently, the inverter
disconnects from the power distribution grid.
Corrective measures:
• Contact installer.
EEPROM Temporary disturbance during reading or writing of data from the
EEPROM.
This data are not essential for safe operation. This message is for
information purposes and has no effect on the performance of the inverter.
EEPROM p EEPROM data are defective.
The inverter has switched off because the loss of data has disabled
important inverter functions.
Corrective measures:
• Contact installer.
EeRestore One of the duplicate records in the EEPROM is defective and has been
reconstructed without loss of data. This message is for information
purposes and has no effect on the performance of the inverter.
