NOTE
:
Replacement
PCB
is
220V/ 240V version
only.
When
existing
PCB
is
100V/117V
version, note the following.
Differences between voltage versions are fuse rate and
fuse labels.
When
fuses
and
labels of specific voltage
(100V/117V)
are required, order separately, referring
to Table.
A
below.
When
using replacement PCB on 100
V
or 117V
version, be sure to
change mark
on PCB
as
shown
in
