overload leading to a fire, and/or cause
damage to electrical components and/or
systems. Contact a smart center if you
encounter any electrical problems.
! A blown fuse must be replaced by an
appropriate spare fuse (recognizable by
its color or the fuse rating given on the
fuse) of the amperage recommended in
the fuse chart. Any smart center will be
glad to advise you on this subject.
If a newly inserted fuse blows again, have
