EEPROM p
Data from the EEPROM is defective.
The inverter has switched itself 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.
Fac-Bfr
Fac-Srr
The AC power frequency has exceeded the permissible range. The inverter
disconnects itself from the power distribution grid to prevent islanding.
Corrective measures:
• Contact installer.
GFDI Fuse Open
The grounding fuse has been tripped.
Corrective measures:
• Contact installer.
Grid-Timeout
Grid-Fault-S
It was not possible to detect the system configuration of the power
distribution grid.
Corrective measures:
• If the message occurs frequently, contact the installer.
Imax
Overcurrent was detected on the AC side.
The current to the power distribution grid has exceeded the specifications.
This may be caused by a serious system incident.
Corrective measures:
• Contact installer.
K1-Close
An internal test has failed.
The inverter disconnects itself from the power distribution grid. As soon as
the error has been remedied, the inverter tries to feed into the power
distribution grid again. If the inverter cannot feed into the power
distribution grid after several attempts, the inverter triggers the permanent
inhibition of operation.
Corrective measures:
• Contact installer.
