CLIF-CBUSLC INTERFACE – INSTALLATION & COMMISSIONING INSTRUCTIONS

C-BUS CONNECTION

The CLIF-CBUSLC features an RS485 interfaces to which C-Bus devices can be connected: RS485-1 (consisting of push-in
terminals 24 [GND-1], 25, and 26).

Via the C-Bus, up to 30 C-Bus devices (e.g., controllers, etc.) can communicate with one another and a PC central. The C-Bus
must be connected via the individual controllers (open ring).
NOTE: Star connection is not allowed, as this might cause uncontrollable line reflections.
Instead of CLIF-CBUSLC Interfaces, C-Bus controllers (e.g., the Excel 500, Excel 100, LION, PANTHER) can also be
connected.
