CLIF-CBUSLC INTERFACE – INSTALLATION & COMMISSIONING INSTRUCTIONS

EN1Z-1026GE51 

R0417 

Connecting CLIF-CBUSLC via RS485-1 to C-Bus 

NOTE:

 

Always power each CLIF-CBUSLC and the connected C-Bus devices via separate transformers. 

NOTE:

 

The max. C-Bus cable length is 1200 m (4000 ft). 

NOTE:

 

If any devices are not electrically isolated, signal ground connection is recommended. See section "RS485 Standard" 
on pg. 11. 

NOTE:

 

If the CLIF-CBUSLC is connected at either of the line's two ends, an additional termination resistor (RT = 120 Ohm) is 
necessary. 

NOTE:

 

Regardless of the position of the CLIF-CBUSLC along the C-Bus, the 3-position switch must be set to MID.
