CAUTION
Before carrying out wiring, turn off the power
to the controller and check that cables to be
connected are not alive with a tester or the like
because there is a possibility of electric shock.

Note: External Contact Input
If the power is turned on when the external contact input is OFF,
the mode (SPN, R/L, or A/M) existing before the power is turned
off will be continued. (except for RUN/STOP)
