3.7.1 Auto fuse
An auto fuse placed just after at the power input protects the eWON devices against short circuits. This component
returns by itself to its normal state when the short circuit has disappeared and after the component has been cooling
down. Would this fuse happen to operate, please check the device for presence of loose metal parts inside likely to
generate a short circuit. If the problem recurs even after such a verification, then return the device to the vendor for
further investigation.
