Mixed operation
Mixed operation (standard/XTR modules) within a node is possible when groups
of modules are electrically isolated on the field side (i.e., electrically isolated
power supply).

Inserting and Removing Devices
Do not work when devices are energized!
High voltage can cause electric shock or burns.
Switch off all power to the device prior to performing any installation, repair or
maintenance work.
5.6.1
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.
