Note for models with a power inlet having a built-in fuse
If the fuse built in the power inlet has blown, the power supply PCB could also be damaged.
Be sure to replace the whole power supply PCB ASSY, not just the fuse. Never use any
substitute or short-circuit the fuse terminals with conductors. Using a power inlet with an
unauthorized fuse will cause a fire or accident.
Assembling Notes:
• Before mounting the MJ shield, route the main-MJ (LINE) and (EXT) harnesses through
the cable guide provided on the MJ PCB insulator. (See the previous page.)
• Route the power cord through the PS insulator 200 V (see below) and the cable guides
provided on the AC cord holder (see the next page). Fit the corner of the PS PCB
insulator into the cutout provided in the lower MJ/PS shield as shown below.
• When mounting the power supply shield on the lower MJ/PS shield, insert two shield
supports of the power supply shield into the two square holes provided in the lower MJ/
PS shield. Make sure that the lock of the lower MJ/PS shield (as shown on the next page)
fits in the slit provided in the top of power supply shield. (See the previous page.)
