Inserting the Fieldbus Coupler/Controller
1.
When replacing the fieldbus coupler/controller for an already available
fieldbus coupler/controller, position the new fieldbus coupler/controller so
that the tongue and groove joints to the subsequent I/O module are engaged.
2.
Snap the fieldbus coupler/controller onto the carrier rail.
3.
Use a screwdriver blade to turn the locking disc until the nose of the locking
disc engages behind the carrier rail (see the following figure). This prevents
the fieldbus coupler/controller from canting on the carrier rail.
With the fieldbus coupler/controller snapped in place, the electrical connections
for the data contacts and power contacts (if any) to the possible subsequent I/O
module are established.
