WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote
disconnects and discharge all motor start/run
capacitors before servicing. Follow proper lockout/
tagout procedures to ensure the power cannot be
inadvertently energized. For variable frequency drives
or other energy storing components provided by Trane
or others, refer to the appropriate manufacturer's
literature for allowable waiting periods for discharge of
capacitors. Verify with an appropriate voltmeter that all
capacitors have discharged. Failure to disconnect power
and discharge capacitors before servicing could result
in death or serious injury.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN.
eFlex™ Compressor VFD Programming
Parameters
The VFD is factory programmed and should not be
modified in the field. It is specifically matched to the
compressor. Should replacing a VFD become necessary,
the replacement is configured with all ofTrane's operating
parameters. Do not use any other type or brand of VFD
when replacing the VFD.
Supply and Exhaust Fan VFD Programming
Parameters
Units shipped with an optional variable frequency drive
(VFD) are preset and run tested at the factory. If a problem
with a VFD occurs, ensure that the programmed
parameters listed in Table 78
replacing the drive.
Note: Check to make sure that parameter 1-23 is set to 60
Hz (or 50 Hz where applicable) and that parameter
0-06 is set to the correct supply voltage/frequency
range.To check parameter 1-23 press the [Main
Menu] button (twice ifTR150 drive) (press [Back]
button if the main menu does not display), use the

Should replacing a VFD become necessary, the
replacement is not configured with all ofTrane's operating
parameters.The VFD must be programmed before
attempting to operate the unit.To verify and/or program a
VFD, use the following steps:
1. At the unit, turn the 115 volt control circuit switch 1S70
to the "Off" position.
2. Turn the 24 volt control circuit switch to the "Off'
position.
Live Electrical Components!
During installation, testing, servicing and
troubleshooting of this product, it may be necessary to
work with live electrical components. Have a qualified
licensed electrician or other individual who has been
properly trained in handling live electrical components
perform these tasks. Failure to follow all electrical
safety precautions when exposed to live electrical
components could result in death or serious injury.
