Description
The internal temperature of the
inverter is too high.
Voltage in DC link is too high.
Fan speed is too low.
Internal error. Voltage
measured before and after the
relay differs too much.
Current measured on AC side
is too high.
Internal error. Voltage
measured before and after the
relay differs too much.
Failure in memory/EEPROM.
Internal communications fault.
Communication error.
Current measured on AC side
is too high.
Internal error.
Failure in memory/EEPROM.
Temperature sensor error.
Measure
Verify that no objects or dust are on
top of the inverter and make sure
that the air ducts are clear and not
blocked.
If the event persists, reset the
inverter by disconnecting DC and
AC. If the event is repeated, check
the maximum DC voltage using the
display to see if it is above the limits.
Check whether the inverter fan is
blocked.
