Wiring Installation
Wiring Best Practices
To ensure proper network communication, follow the recommended wiring 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.e
•
In open plenums, avoid running wire near lighting ballasts, especially thos using 277 Vac.
•
Use Trane purple communication wire without terminators, for the zone sensor communication
stubs from Symbio 210 controller IMC terminals to the zone sensor communication module.
•
Zone sensor communication wiring length limit of 328 feet (100 meters).
Setting the Symbio 210 Controller on a Daisy Chain BACnet/IP Link
Observe the following when setting up the Symbio 210 controller on a daisy chain BACnet/IP link:
•
Use CAT5 or CAT5e non-shielded twisted pair, Ethernet cable with RJ45 connectors for BACnet/
IP installations.
•
Cable length limit is 100 meters (328 feet)
•
Connect the Ethernet cable coming into the Symbio 210 controller RJ45 jack marked #1.
Connect an Ethernet cable going to the next controller in the daisy chain to the RJ45 jack marked
#2. See
Setting the Symbio 210 Controller on a Home Run BACnet/IP Link
Observe the following when setting up the Symbio 210 controller on a home run BACnet/IP link.:
•
Use CAT5 or CAT5e non-shielded twisted pair, Ethernet cable with RJ45 connectors for BACnet/
IP installations.
•
Cable length limit is 100 meters (328 feet).
•
Connect the Ethernet cable from the Symbio 210 controller RJ45 jack marked #1 back to the
switch port dedicated for this controller. See
