Emerson Liebert iCOM Manual De Usuario

No special considerations are required for cable up to 150 ft. (45m) long. A CANbus isolator is 

required for cables between 150 ft. and 300 ft. (45m and 91m). Contact the factory if using CANbus 

cables longer than 300ft (91m).
The CANbus cable network requires a ground wire. The grounds are connected at each 2T sensor and 

must be terminated to a field-installed ground ring in the low-voltage electrical panel. Figure 74 

shows the connected grounds on a 2T sensor.

Follow these guidelines when routing CANbus cable to ensure reliable communication.

• Use approved hangers, such as telephone wire/RG-6 coaxial wired hangers; do not secure cables 

with any method that might damage them.

• Limit bends to less than four times the diameter of the cable.
• Avoid deforming cables when securing in bundles and when hanging them.
• Keep cables away from devices that may introduce interference, such as high-voltage wires, 

machines, fluorescent lights, and electronics. High-voltage sources must be at least 12 inches 

(305mm) from CAN wires.

• Avoid stretching cables.
• Ensure that cables have the correct pin-outs. Mismatching wire pins at the RJ12 connection will 

damage the CAN device.

Cables may be purchased from your local Emerson distributor.
