Note for models with a power inlet having a built-in fuse
When replacing a fuse built in the power inlet, be sure to use a specified one. 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
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.)
