3.8.1 Auto fuse
An auto fuse placed just after 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.
