(1) The V terminals on the left and right for the I/O power supply, as well as
the G terminals on the left and right for the I/O power supply are not con-
nected internally. Supply power separately for V-G terminals on the left
side and the right side.
(2) When using an inductive load (such as a solenoid valve), either use a
built-in diode for absorbing the counterelectromotive force or install an ex-
ternal diode.
(3) Do not wire NC terminals.
(4) Wire colors have been changed according to revisions in the JIS stan-
dards for photoelectric and proximity sensors. The colors in parentheses
are the wire colors prior to the revisions.
