3.1.12 Removing the DCDC control board
(See Fig.10)
• Remove the top cover.
Reference:
Remove the tie band bundling the wires.
Disconnect the connector CN151
from the main amplifier board in an upward direction.
Note:
When removing the DCDC control board, take care not to
break the claw of the connector on the main amplifier board.
3.1.13 Removing the PWM modulation 1 board
(See Fig.11)
• Remove the top cover.
Reference:
Remove the tie band bundling the wires.
(1) Disconnect the wire from the connector
PWM modulation 2 board.
(2) Disconnect the wires from the connectors (CN311, CN312,
CN313) on the PWM modulation 1 board.
(3) Disconnect the connector
1 board from the main amplifier board in an upward direc-
tion.
Note:
When removing the PWM modulation 1 board, take care not to
break the claw of the connector on the main amplifier board.
3.1.14 Removing the PWM modulation 2 board
(See Fig.11)
• Remove the top cover.
(1) From the top side of the main body, disconnect the wires
from the connectors (CN411, CN412, CN413) on the PWM
modulation 2 board.
(2) Disconnect the connector
2 board from the main amplifier board in an upward direc-
tion.
Note:
When removing the PWM modulation 2 board, take care not to
break the claw of the connector on the main amplifier board.
