1) Values at a switching current of 3.5 A without taking into account the cable lengths.
2) After the operating voltage is switched on, the semiconductor outputs are switched off during the ready delay.
3) The dwell time of an actuator inside and outside the actuating range must be at least 0.5 s to ensure reliable detection of internal faults in the evaluation unit (self-monitoring).
