Wiring Best Practices
To ensure proper network communication, follow the recommended wiring and best practices
below when installing communication wire:
•
All wiring must comply with the National Electrical Code™ (NEC) and local codes.
•
Ensure that 24 Vac power supplies are consistent in regards to grounding. Avoid sharing 24 Vac
between controllers.
•
Avoid over tightening cable ties and other forms of cable wraps. This can damage the wires
inside the cable.
•
Do not run communication cable alongside or in the same conduit as 24 Vac power. This
includes the conductors running from TRIAC-type inputs.
•
In open plenums, avoid running wire near lighting ballasts, especially those using 277 Vac.
•
Use same communication wire type, without terminators, for the zone sensor communication
stubs from the UC210 controller IMC terminals to the zone sensor communication module.
•
Zone Sensor communication wiring length limits of 300 ft. (100 m).
Note:
For more details, refer to the BACnet Best Practices and Troubleshooting Guide
(BAS-SVX51-EN).
