6.4 Replace the Fuse
When there is something wrong with the device, the fuse can effectively protect the key components,
and separate the fault from the system to avoid the fault expanding. If the fuse is damaged, it is
necessary to replace the fuse that with the same type or passed the safety criterion and with the same
character on the basis of corresponding rules. The fuse fusing character and disjunction capacity of the
fuse used in input end, output end, battery input end of this series device are as follows:
Battery input: fuse 660GH/660V/315A, disjunction capacity: 100KA. The fusing characteristics are as
follows.
Mains input, bypass input, output: fuse 660GH/660V/400A, disjunction capacity: 100KA. The fusing
characteristics are as follows.
Charging end: fuse 660GH/660V/100A; disjunction capacity: 100KA. The fusing characteristics are as
follows.
