By the use of PELV power units, protection against electric shock (protection against direct and indirect contact) is guar- anteed with the Festo valve terminals in accordance with EN 60204-1/IEC 204. Safety transformers with the adjacent symbol must be used for supplying PELV networks. The valve terminals must be earthed to ensure that they function cor- rectly (e.g.
