Note
• Only use connection accessories with a straight plug
(Accessories è www.festo.com/catalogue) at electrical connections 3
and 6.
If using the energy throughfeed with electrical connections DRRD−...−P..E..:
• Connect lines to electrical connections 3 and 6.
Corresponding port identifications (A) are used to indicate which plug to plug
into which socket.
