Angle the terminal socket at the upper edge of the DIN
rail until it snaps in.
Swing the terminal socket down and apply gentle force
until it snaps into position with an audible "click".
Position controller module and terminal sockets flush with
one another along the rail.
If desired, mount stoppers at the ends of the rail to
Mounting terminal sockets
Take care to not bend the Omega clamp, which serves to
establish the electrical contact with the DIN rail and which
located on the back of the terminal socket.
Controller, terminal sockets, and mixed I/O modules on the
same DIN rail can be connected mechanically and
electrically with bridge connectors.
Controller and terminal sockets on different DIN rails must
be connected using cables, see Fig. 14 and page 25.
Risk of malfunction!
Wire Panel Bus I/O modules and L
I/O modules separately.
When using both Panel Bus and L
I/O modules in a LION System, L
I/O modules must be connected to the controller via
LON terminals 11 ... 14.
Position the bridge connector on terminals 71 ... 74 of the
right hand terminal socket or mixed I/O module or controller
and on terminals 75 ... 78 of the left hand terminal socket or
mixed I/O module or controller. Then press the bridge
Connecting terminal sockets with bridge
• Bridge connectors transmit both communication signals
and power supply between modules.
• Removing bridge connectors will interrupt the trans-
mission of both communication signals and power supply
between the modules.
