power supply).

Inserting 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.
6.6.1

Inserting the Controller

1. When replacing the controller for an already available controller, position
the new controller so that the tongue and groove joints to the subsequent
I/O module are engaged.
2. Snap the 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 controller from canting on the carrier rail.
With the 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.
