0400H Manual Stop
The inverter has been manually stopped. Check that the manual shutdown has not been enabled and, if it
has, go to the display and remove it.
0001H Vin out of range
0002H Grid frequency out of range
0004H Grid voltage out of range
The most likely reason is a Grid power failure. Account should be taken of the fact that the alarms are
added together. Therefore, when this failure occurs, the alarm shown will be 0006H, resulting from the
sum of 0002H + 0004H.
When it returns to normal, the inverter will start functioning again. If this is not the case, check the Grid
connection lines.
If the grid quality parameters are adequate, then check the grid connection lines.
If the error persists, contact Ingeteam Inc
0020H DC circuit insulation failure
This can be due to one of three causes:
• Insulation failure in the panel circuit.
• The thermal fuse varistor has been triggered.
• The differential current or default current protective device has been triggered.
CAUTION
An insulation failure can be life threatening.
An Insulation Failure must be repaired by qualified personnel.
Procedure to determine the exact cause of the insulation failure:
• Check that the insulation failure is not in the panel circuit by disconnecting the various panel
strings from the circuit.
• If feasible, connect the inverter to another panel circuit which is functioning correctly.
• If the failure persists, measure the voltage between each string in the panel array and ground.
• If the voltage measured is constant and approximately coincides with the open circuit voltage,
then there is an ground fault in that string. This needs to be checked for each string.
• If the failure persists after correcting the ground faulty, then the thermal fuse - varistor protection
needs to be checked.
For the following check, pay particular heed to the following warning notice:
CAUTION
The inverter houses electric capacitors which can maintain high temperatures, even after
the inverter has been disconnected from the panels and grid. After disconnection, always
wait 30 minutes before opening the unit.
Procedure for determining the cause of the insulation failure:
1. Disconnect the panel circuit from the inverter.
2. Open the inverter, heeding the safety warnings contained in this section, and treating the opera-
tion as a Manipulation procedure by applying the rules for Manipulation operations set out in section
"4. Safety instructions".
3. Remove the varistors.
