1. WARNING

To prevent the risk of fire, smoke, or electrical shock and to ensure safe operation, please be sure to
follow the safety guidelines below.
1. At places where special caution is required, the necessary safety

electric switch, electrical cord, noise-prevention condenser, etc.), wind
the lead wire and secure it by soldering.
5. Do not let the wiring come into contact with heat-emitting devices
(fuse resistor, radiator plate, etc.).
6. When replacing the wiring, make sure that it is not in contact with the
unfinished or rough edge of a part.
7. When replacing the power cord (except for the plug-in type), tug it
from various directions to confirm that it does not slip out of place.
8. Spacing
If soldering was done on the AC primary circuit, confirm that the
interval between the soldered terminals or between the terminal and
surrounding metallic parts is at least the minimum required (between
the primary circuit and the chassis: at least 6.5 mm; between primary
circuit terminals: at least 4.0 mm; between primary circuit terminals
and secondary circuit terminals: at least 6.5 mm.).
