1) Contactors installed by the user will have an effect on the safety data.
2) PFH values according to EN ISO 13849.
3) In low demand mode, DC of electromechanical devices is considered as 0%, and therefore no overall DC value is claimed
in low demand mode.
4) See also the Recommendation of Use CNB/M/11.050 published by the European coordination of Notified Bodies for lower
T requirement.
