Plan wiring runs for Unit-to-Module (U2M) communication when designing the layout of the
conditioned space. In addition to general good wiring practices, take into account:
• Keep control and communication cables away from power cables to prevent electromagnetic
interference.
• Do not bend cables to less than four times the diameter of the cable.
• Do not deform cables when securing in bundles or when hanging them.
• Keep cables away from devices that can introduce noise into them, such as machines,
fluorescentlights, and electronics.
• Avoid stretching cables-tension when pulling cables should not exceed 25 pounds (11kg).
• Do not secure cables with any method that might damage them; use approved hangers, such as
those used for telephone wire and RG-6 coaxial wire; available at most hardware stores.
• Do not run cables through conduit. Cables should be treated the same as any other data cable.
Running CANbus cables through conduit will increase the total length required.
