IFM Electronic AS-i CONTROLLERe AC1027 Notice De Montage page 10

Ensure a condensation-free environment. Avoid excessive dust,
vibration and shock. The air circulation through the vents must
not be impeded.
Avoid installation in direct vicinity of frequency inverters.
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.
