Safety Relays ESM General information For machines and installations that can produce a risk for people when in operation, the EU Machinery Directive defines minimum requirements that are intended to reduce to a minimum the specific hazards and the related risks of accident. If all sources of danger cannot be eliminated by design measures, appropriate protective measures must be taken. Using guards, such as fences or similar, it is intended to prevent personnel from entering the danger area. If users need to have access to the danger area during operation, movable guards such as safety doors,...
