Installation position Permissible installation position Each actuator is unique. The switch detects only taught-in actuators. Additional actuators can be taught in. Only the last actuator taught in is detected. Category according to EN 13849-1 Due to two redundantly designed semiconductor outputs (safety outputs) with internal monitoring suitable for:

• Category 4/PL e according to EN 13849-1

Important: To achieve the stated category according to EN ISO 13849-1, both safety outputs (FO1A and FO1B) must be evaluated. LED indicator
