Page 19: On Delay
Faulty tripping of channels that are connected in parallel may occur on the supply side with capacitive loads that are not protected against reverse discharge. • In this case, WAGO recommends taking suitable measures (e.g., a diode or MOS- FET) to decouple the capacitive load. 4.3 On Delay As soon as a minimum input voltage is present, the channel is activated with a time de- lay. -
