An RS-422A/485 Option Board can be mounted to an Option Board slot on
the CPU Unit. With a CPU Unit with 30 or 40 I/O points, either Option Board

When mounting an Option Board, first remove the slot cover. Grasp both of
the cover's up/down lock levers at the same time to unlock the cover, and then
pull the cover out.
Then to mount the Option Board, check the alignment and firmly press it in
until it snaps into place.
!Caution
Always turn OFF the power supply to the PLC before mounting or removing
an Option Board.
