The power isolating device can be operated locally to perform the emergency stop function in accordance with EN 60204-1 Safety of machinery - Electrical equipment of machines - Part 1: General requirements' where it is stated in section 10.7.4 'Operation of the power isolating device to perform an emergency stop'.\\\\r\\\\n\\\\r\\\\nHowever, when the switch disconnector is used as an emergency stop, it makes no sense to speak of a reliability level according to ISO 13849-1 or IEC 62061. The reason is that this component is not part of the machinery control system, since it only acts on the power side.\\\",\\\"_text_block\\\":\\\"_acf_field_text_block_bow-gte-testo-media\\\",\\\"image_block\\\":42609,\\\"_image_block\\\":\\\"_acf_field_image_block_bow-gte-testo-media\\\",\\\"align_image\\\":\\\"left\\\",\\\"_align_image\\\":\\\"_acf_field_align_image__bow-gte-testo-media\\\",\\\"floated_image\\\":\\\"1\\\",\\\"_floated_image\\\":\\\"_acf_field_floated_image__bow-gte-testo-media\\\",\\\"image_max_width\\\":\\\"33\\\",\\\"_image_max_width\\\":\\\"_acf_field_image_max_width__bow-gte-testo-media\\\",\\\"content_max_width\\\":\\\"50\\\",\\\"_content_max_width\\\":\\\"_acf_field_content_max_width__bow-gte-testo-media\\\",\\\"repeater_call_to_action_group\\\":\\\"\\\",\\\"_repeater_call_to_action_group\\\":\\\"_acf_field_repeater_call_to_action_group_bow-gte-testo-media\\\"},\\\"mode\\\":\\\"auto\\\"} \\\/-->\\n\\n<!-- wp:acf\\\/bow-gte-testo-media {\\\"name\\\":\\\"acf\\\/bow-gte-testo-media\\\",\\\"data\\\":{\\\"base_fields_group_is_preview\\\":\\\"0\\\",\\\"_base_fields_group_is_preview\\\":\\\"_acf_field_is_preview\\\",\\\"base_fields_group_status_block\\\":\\\"preview\\\",\\\"_base_fields_group_status_block\\\":\\\"_acf_field_status_block_bow-gte-testo-media\\\",\\\"base_fields_group_id_block\\\":\\\"\\\",\\\"_base_fields_group_id_block\\\":\\\"_acf_field_id_block_bow-gte-testo-media\\\",\\\"base_fields_group_color_background\\\":\\\"default\\\",\\\"_base_fields_group_color_background\\\":\\\"_acf_field_color_background_bow-gte-testo-media\\\",\\\"base_fields_group_spacing_block\\\":\\\"base\\\",\\\"_base_fields_group_spacing_block\\\":\\\"_acf_field_spacing_block_bow-gte-testo-media\\\",\\\"base_fields_group\\\":\\\"\\\",\\\"_base_fields_group\\\":\\\"_acf_field_base_fields_group_bow-gte-testo-media\\\",\\\"repeater_heading_group\\\":\\\"\\\",\\\"_repeater_heading_group\\\":\\\"_acf_field_repeater_heading_group_bow-gte-testo-media\\\",\\\"text_block\\\":\\\"\\\\u003cu\\\\u003e\\\\u003cstrong\\\\u003e13.
