6.5. FUSE SELECTION
Blown fuses typically indicate a semiconductor device failure or a severe transient. In
any case, blown fuses should not be replaced without first consulting Bonitron as
catastrophic damage can occur. Use Tables 6-6 and 6-7 when initially constructing
the system.
Note: AC fuses must be J-type or equivalent.
