How do I clear fault code 0070 interlock activated on PV inverter?

Issue:
The inverter faulted on interlock activated 0070 and unable to clear with F1 button
 
Product Line:
PVxxx
 
Environment:
 
Cause:
Loose connection or defective component

Resolution:
First, perform LOTO to make sure all energy in the inverter is zero. Look at the foam around the inverter door and see if it is still thick. Id it is broken off or seems shrunk then that is why the fault occurred because it is not thick enough to pushed in the door switch. Buy a piece of foam like it and install it where the door switch is located.
