Communication Wiring
Follow these guidelines when installing communication wiring:
• The communication wire shield must be connected to the ground terminal of the link termination block at the Tracer
®
for the BACnet link.
• It is best practice to tape back the shield conductor at the terminator and each end of the link as illustrated in
Important: Never connect the shield conductor to ground at the Tracer
• Tie shield conductors together and tape back at each BACnet
®
• BACnet communication wiring can be terminated on LINK 1 or LINK 2 on the Tracer
