X-SUS Circuit Board Removal/Installation Procedure
When removing the circuit board after the main power is turned on/off, wait for at least
one minute before starting to remove the circuit board.
If the circuit board removal is started immediately after turning off the main power,
it can result in electric shock or damage to the circuit due to residual electric charge.
Remove the circuit board following the steps below. To install the circuit board, reverse
the removal procedure.
(1)
Remove the fixing screws (M3×8) at 9 locations.
(2)
Release the lock of the FPC connector (CN21) and disconnect the signal cable.
(3)
Disconnect the cables from the VH connectors (CN22, CN23).
(4)
Pull out the XSUS board horizontally and disconnect the connectors (CN24, CN25).
Note
* On handling the FPC connector
To release the lock, release it by gently flipping
it with the nail of the thumb or forefinger.
Never pinch the lock lever with fingers or hook on
it (especially with a fingernail).
Doing so might damage the lock lever.
