Annex C
(normative)

Safety categories in accordance with EN 954-1

This normative annex has been prepared under the following assumptions:
 The risk assessment has been based on the risk graph in annex B of EN 954-1:1996.
 Only category B has been selected in accordance with EN 954-1:1996 if more than one measure is stipulated
in EN 528 to fulfil the safety-related functions.
 Safety categories for motors, brakes and other structural elements, e.g. end stops, have not been taken into
account.
 The safety categories reflect the state of the art.
