Notes:
• Both STO inputs (IN1, IN2) must be connected to the activation switch. Otherwise, no
SIL/PL classification is given.
• Pay special attention to avoiding any potential failure modes for the wiring. For example,
use shielded cable. For measures for fault exclusion of wiring, see eg. EN ISO 13849-
2:2012, table D.4.
