General Information
Control Solutions
Performance air handlers are available with an optional control
interface. This package can be used as part of a stand-alone
operation, or it can be fully integrated into a comprehensive
control system. The Trane EarthWise™ system incorporates
the benefits of factory-installed controls and links the air
handler to the Tracer® SC system controls building
management system. This option is designed to lower
installation costs and risk while dramatically improving the
quality of the application and the performance of the air
handler. The entire air handler control system is engineered,
mounted, wired, and tested before leaving the factory. As a
result of strict quality manufacturing methods, these control
options bring consistency and reliability to the control-system
package and provide single-source responsibility.

•
Trane UC600 controller

Wiring
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 electrical codes.
WARNING
Electrical Shock Hazard!
Failure to follow instructions below could result in
death or serious injury.
Properly connect the system's oversized protective
earthing (grounding) terminal.
Entrances are generally provided for field-installation of high
and low voltage wiring through a pipe/nipple connection in the
unit depending on unit configuration with or without factory-
mounted controls. Before installation, consider overall unit
serviceability and accessibility before mounting, running wires
(power), making penetrations, or mounting any components to
the cabinet.
Wiring to the air handler must be provided by the installer and
must comply with all national and local codes. The fan motor
nameplate includes a wiring diagram. If there are any
questions concerning the wiring of the motor, write down the
information on the motor nameplate and contact your local
Trane sales office.
