►  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 
prevent sliding.

Note 
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. 
 
Connecting Sockets 
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. 
 
NOTICE 
Risk of malfunction! 
►  Wire Panel Bus I/O modules and LONWORKS Bus 
I/O modules separately. 
►  When using both Panel Bus and LONWORKS Bus 
I/O modules in a LION System, L
ONWORKS Bus 
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 
connector down.

Notes 
•  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.
