IFM Electronic AS-interface AC1321 Notice De Montage page 10

Electrical connection
Disconnect the installation from power. Connect the unit as indi-
cated on the terminals. Never connect the minus potentials to
each other or the minus potentials to the FE connection. Ensure
an electrically safe ground connection between AS-i controller
(terminal FE) and ground of the unit.
Supply the CANopen controller
Connection is made to the terminals +24 V and 0 V.
