Note
Loss of the safety function!
Lack of the safety function can result in serious, irreversible injuries, e.g. due to uncon
trolled movements of the connected actuator technology.
Bypassing of safety equipment is impermissible.
Make sure that no jumpers or the like can be used parallel to safety wiring, e.g. through use of
maximum wire cross sections or appropriate wire end sleeves with insulating collars.
Use twin wire end sleeves for looping through lines between neighbouring equipment.
