Wiring and Powering the Tracer UC600

This section describes how to wire and safely power the UC600.
Important: If problems occur after powering refer to the troubleshooting section,
Tip:

AC Power Warnings and Cautions

Hazardous Voltage!
Disconnect all electric power, including remote disconnects, before servicing. Follow proper
lockout and/or tagout procedures to ensure the power cannot be inadvertently energized.
Failure to disconnect power before servicing could result in serious injury or death.
Personal Injury and Equipment Damage!
After installation, verify that the 24 VAC transformer is grounded through the controller. Failure
to do so could result in personal injury and/or damage to equipment. Measure the voltage
between chassis ground and any ground terminal on the controller. Expected result: VAC
Refer to the section,
Notice:
Equipment Damage!
Complete input/output wiring before applying power to the UC600 controller. Failure to
complete this task may cause damage to the controller or power transformer due to inadvertent
connections to power circuits. The designed units accept only copper conductors. Other types
may cause equipment damage. Do not share 24 VAC between controllers. Sharing 24 VAC power
may cause controller damage (refer to the section,

Requirements and Recommendations

Wiring and Circuit Requirements

All wiring must comply with the National Electrical Code and local electrical codes.
To ensure proper operation of the Tracer UC600, observe the following guidelines:
•
•

•
BAS-SVX45F-GB
"Commissioning/Troubleshooting in a Powered State, " p.
Before powering the UC600, read sections,
"Power Budget Check in an Un-powered State, " p.
WARNING
CAUTION
"Wiring AC Power to Tracer UC600," p.
The controller should receive AC power from a dedicated power circuit; failure to comply may
cause the controller to malfunction.
A dedicated power circuit disconnect switch must be near the controller, easily accessible by
the operator, and marked as the disconnecting device for the controller.
Do not run AC power wires in the same wire bundle with input/output wires; failure to comply
may cause the controller to malfunction due to electrical noise.
18 AWG (1.02 mm diameter) copper wire is recommended for the circuit between the
transformer and the controller.
