Risks must be reduced by designing and implementing the machine accordingly (e.g. by
means of controllers or protective measures suitable for the safety-related functions).
If the protective measures involve the use of interlocking or control functions, these must be
designed in accordance with EN ISO 13849-1:2006. For electrical and electronic controls,
EN 62061 can be used as an alternative to EN ISO 13849-1:2006. Electronic controls and
bus systems must also comply with IEC/EN 61508.
