General Information
Wiring
WARNING
Grounding Required!
All field-installed wiring must be completed by qualified personnel. All field-installed wiring
must comply with NEC and applicable local codes. Failure to follow these instructions could
result in death or serious injuries.
There are no penetrations into the M-Series air handler for any field-provided wiring or device.
Before installation, consider overall unit serviceability and accessibility before mounting, running
wires (power), making cabinet penetrations, or mounting any components to the cabinet.
Wiring to air-handling unit must be provided by the installer and must comply with all national and
local electrical 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.
Controls
Factory-Mounted Controls
Small items that cannot be factory mounted will ship inside the control enclosures. Larger items
may ship inside the fan module.
Note:
All control valves ship directly to the “ship-to address” from the vendor unless another
address is given on the Trane sales order.
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
line 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 120. 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.
For a more in-depth understanding of controls, refer to the following manuals:
•
For programmable MP580 controllers, CNT-SVP01A-EN
•
For hardware installation, CNT-SVN01A-EN
•
For Danfoss VFD, TR1-SVX10A-EN
Pre-Packaged Solutions
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.
