If a fault occurs in the inverter, the current fault indicator will
be shown in the display. The top line shows the numeric code
of the fault, and the second line gives a fault indicator. The
faults listed cause the inverter to switch off. It normally
switches back on automatically once the fault has been
cleared. If the inverter does not switch back on or you cannot
clear the fault, contact the manufacturer's service centre
(contact information on the back of the manual).
