Pre-Packaged Solutions For Controls; Wiring - Trane Performance Climate Changer Installation, Operation And Maintenance Manual

General Information
All factory-mounted control systems (controls that are factory-wired to a unit controller or
termination strip) ordered without starters or variable-frequency drives (VFDs) are provided with
120 to 24 Vac control transformers mounted and wired in the auxiliary control panel. The customer
must provide 120 Vac control power, 50/60 Hz, typically 3 amps for unit sizes 3 to 57 and 5 amps
for unit sizes 66 to 100. A dedicated 15-amp circuit is recommended.
Factory-mounted control systems ordered with factory-mounted starters or VFDs are supplied with
line to 24 Vac control transformers. No additional power wiring is required.

Pre-Packaged Solutions for Controls

If the air handler has been selected using one of Trane's pre-packaged solutions options for
controls, there are a number of resources available to aid in commissioning and start-up of the unit.
These resources include commissioning sheets, graphics and technical application notes. The
technical application notes include the control sequencing, Trane Graphic Programming (TGP) and
Rover set-up files for the specific unit selected. These resources are available through your local
Trane sales office.

Wiring

Proper Field Wiring and Grounding Required!
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. Failure to follow codes could result in death or serious injury.
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.
