NOTE: When using both Panel Bus and LONWORKS Bus
I/O modules in an Excel 800 System, group both
Panel Bus modules (light-gray) and L
ONWORKS
Bus I/O modules (dark-gray), e.g., on different
rails. Up to 10 Panel Bus I/O modules can be
mounted to one side of the XCL8010AU. In total,
up to 16 Panel Bus I/O modules can be mounted
to one controller. The XCL8010AU Controller
Module is mounted on the DIN rail in the same way
as a terminal socket.

► 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 XCL8010AU Controller Module and terminal

► 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 and terminal sockets 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.
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 an Excel 800 System, L
ONWORKS Bus
I/O modules must be connected to the XCL8010AU
Controller Module via LON terminals 11 ─ 14.
Position the bridge connector on terminals 71 ─ 74 of the
right hand terminal socket or XCL8010AU Controller Module
and on terminals 75 ─ 78 of the left hand terminal socket or
XCL8010AU Controller Module. Then press the bridge
connector down.
