(6) For 100 V series As shown below, unlatch the power cord bush and pull it up from the AC
cord holder. Then release the power cord from the cable guides provided on the AC cord
holder (shown on
(7) Release the power supply shield from the lock and two stoppers on the lower PS/MJ frame
and pull it up.
(8) Disconnect the power supply harness from the power supply PCB.
(9) Remove three screws "c," take the power supply PCB and PS PCB insulator off the lower
PS/MJ frame, and then remove the power supply harness from the lower PS/MJ frame.
(10) For 100 V series Remove screw "a" and take the MJ shield off the lower PS/MJ frame.
For 200 V series Remove screw "a" (that secures the MJ shield and power inlet) and
screw "d" (that secures the grounding wire). Then take the MJ shield and power inlet off
the lower PS/MJ frame.
Note: If the EXT cap has not been removed, remove it beforehand.
(11) Remove the AC cord holder.
Note: If the AC cord holder has a band, cut it off.
(12) Disconnect the MJ (LINE) harness
release them from the cable guide on the MJ PCB insulator.
