1. Strip wires to expose 0.28 inch (7 mm) of bare wire.
2. Insert the wire into a terminal connector.
3. Tighten the terminal screw to 0.5 to 0.6 N-m (71 to 85 ozf-in or 4.4 to 5.3 lbf-in.)
4. Tug on the wires after tightening the screws to ensure all wires are secure.
BACnet® MS/TP Communication Link
For more details about BACnet MS/TP communication link, refer to the BACnet MS-TP Wiring and Link
Performance Best Practices and Troubleshooting Guide (BAS-SVX51).
WARNING
Proper Field Wiring and Grounding Required!
Failure to follow code could result in death or serious injury.
All field wiring MUST be performed by qualified personnel. Improperly installed and grounded
field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST
follow requirements for field wiring installation and grounding as described in NEC and your
local/state/national electrical codes.
BACnet/IP Over Wired Ethernet Communications
Wired Ethernet is only an option on the Symbio 500 controller. Use daisy chain, star, or ring topologies.
Air-Fi Wireless BACnet® Communications
Symbio 500 can communicate wirelessly to the Trane Tracer SC+ and zone sensors through the Trane
Air-Fi Wireless system (BACnet/Zigbee). Wireless Air-Fi communications are the preferred method of
communicating to the SC+. Trane Air-Fi is a factory or field installed option.
See Air-Fi Wireless System IOM BAS-SVX40*-EN for detailed information.
Wiring Guidelines for Wired BACnet MS/TP
• Use 18 AWG Trane purple-shielded communication wire for BACnet installations.
• Link limit of 4,000 ft and 60 devices maximum (without a repeater).
• Use a Trane BACnet termination on each end of the link.
• Use daisy chain topology.
• Maintain polarity.
