A distinction is drawn here between protection against direct contact, protection against indirect contact and protection against both direct and indirect contact.
- Protection against direct contact
These are all the measures for the protection of personnel and working animals from dangers which may arise from contact with live parts of electrical equipment. - Protection against indirect contact
This is the protection of personnel and working animals from dangers which may arise from accidental contact with components or extraneous conductive parts.
Protection must be ensured by either a) the equipment itself or b) the use of protective measures when erecting the installation or c) a combination of a) and b).
