Switch must meet the conditions of the standard IEC 60947-5-1 (Appendix K).
► Select the input and output circuits according to the max. safety classification (SIL / cat. /
PL).
► If several MS-2 are connected, the test signals must be different.
► Observe current standards of the country in which the AC412S automation system is to
be operated.
► 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.
