If changes occur in the system, such as adding, deleting, and replacing an optimizer, adjusting
the physical position of an optimizer, or adjusting the PV string connected to the solar inverter
input, turn off the DC and AC switches of the inverter and wait for 5 minutes before performing
the operation to avoid personal injuries. After the change is performed, the optimizer search
process must be performed again and the physical layout diagram must be updated. Otherwise,
the networking is incomplete, optimizer faults cannot be located, or the system fails.
