Wire Size System Components Wiring
Wire Size
The AC wire size required for powering CFN system components must be 14 AWG or larger.
This gauge of wire is sufficient for runs of up to 300 feet from the breaker panel to the system.
Components with distances over 300 feet must use 12 AWG wire or larger. All wires should be
stranded.
Specifications for the RS-485 data loop and RS-232 communication wire/cable size are
available in
Communication Requirements .
Communication Requirements
The CFN System utilizes RS-485 and RS-232 modes of communication for communicating to
other CFN system components and peripheral equipment. Specific requirements for each of
these modes of communication can be found in the appropriate Site Controller Installation
Manual.
RS-485 wiring is used for communication between CFN system components. This
communication takes place over the RS-485 modular cables provided with system
components and the RS-485 data loop field wiring. These cables are not compatible with
standard phone cables that are obtained from other sources.
Gasboy-supplied cables are 8 feet long. If you need to connect a CFN component with a
modular connector (that is, console) more than 8 feet away from the system, you must use an
RS-485 junction box to connect the device to the RS-485 communication wiring.
