2 Function and application
The energy throughfeed DRRD-...-P..E.. serves to permit the passage of com
pressed air and electrical signals through the drive shaft of the DRRD semi-rotary
drive.
3 Installation
3.1 Installation, mechanical
 Affix the DRRD with two screws to holes 1and with 2 centring sleeves to the
housing 7.
 Affix the working load with at least two screws positioned opposite one another
to the drive flange, and with centring sleeves to threads 4.
Tightening torques are shown in the table below.

3.2 Installation, pneumatic
If using the energy throughfeed with pneumatic connections DRRD−...−P. . :
 Connect tubes to pneumatic connections 2and 5.
Corresponding port identifications are used to indicate which tube to fit to
which push-in fitting (tubing dimensions èFig. 8).

3.3 Installation, electric
Warning
Danger of short circuit! If one of the electrical inputs 6is supplied with voltage,
there will be voltage at all electrical inputs, because the positive and negative
lines are connected together inside the component.
 Ensure that the electrical inputs 6share a common voltage source.
Otherwise the DRRD may be irreparably damaged by large compensating
currents.
 Leave the cover caps on the unused plugs 6.
The plugs 6on the side of the housing are not protected in any other way
against accidental contact.

Note
 Only use connection accessories with a straight plug
(Accessories èwww.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 3and 6.
Corresponding port identifications (A) are used to indicate which plug to plug
into which socket.
