TBN Wiring Diagram:
NOTE:
1. Dashed lines indicate new field wiring. Sold lines indicate
existing wiring to remain or new field wiring by others.
2. All field wiring must meet or exceed the requirements of the
National Electrical Code (NEC) and the Sate Local requirements.
3. For inputs and outputs, the shield wire is grounded at the
controller end only.
4. Wiring for inputs and outputs is 18 AWG, shielded, twisted pair
with stranded tinned copper conductors.
5. The BACnet
®
MS/TP network wire is 24 AWG (0.65 mm)
stranded, twisted shield pair (Jackson system part#: 24/2
BACnet
®
). The BACnet
®
MS/TP communication wire is polarity
sensitive and the only acceptable topology is to Daisy-chain the
cable from one controller to the next.
6. Mount space temperature sensor per ADA requirements. Field
verify location and coordinate with other trades.
