outside.
Route the EXHAUST FAN cable
over the power supply block cover.
(Observe this precaution to prevent
the secondary side part (EXHAUST
FAN cable) from coming into contact
with the primary side part (circuit
power supply C113)).
To prevent the TSW cable from being caught
by the front bezel, shift it rearward when
you route it after completion of setup.
Ensure that the connector and housing
(marking) match in color (black).
Exercise care to avoid capture.
