► Note the supply voltage limits of the sensor.
► Select the input circuits according to the max. safety classification (SIL / cat. / PL).
When the indicated ifm articles are used, the maximum safety classification according to the
SIL/Cat./PL values listed in the table can be achieved. Note the current standards.
► If other than the indicated products are used, note the current standards.
► Test the safety function within the two-error occurrence time.
The second-error occurrence time takes 24 hours. Within this time the safety function of
the device should be requested once.
