this reason, always keep a disconnected operating unit in a safe place.
ƒ The force−opening switching contacts of the stop key have to be
interconnected in a way that they meet the safety category in accordance
with EN 954−1, which has been determined on the basis of the risk
analysis of the machine in accordance with EN 1050.

ƒ The safety category 3 in accordance with EN 954−1:1996 can be achieved
by means of the confirmation key (confirmation via 2 circuits).
