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 DIN-rail locking cam(s) until the nose(s)
of the locking cam(s) engage(s) 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.
