IFM Electronic AS-interface AC1327 Notice De Montage page 11

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 save ground connection between AS-i controller
(terminal FE) and ground of the unit.
Supply the controller
from the 24 V power supply DN2011 of ifm electronic. The connection
is made to the terminals +24 V and 0 V.
