Electrical Connection - IFM Electronic AS-interface AC2257 Notice De Montage

Addressing
At the factory the address is set to 0.
Addressing with the addressing unit AC1154
When mounted and wired the module can be addressed by connect-
ing the addressing cable (E70213) to the implemented addressing
socket.
Do not remove the addressing plug while live.

Electrical connection

Disconnect power! Connect the sensors and actuators with the
