PART-SVN121A-EN 7
Removing the Existing VFD and Components
WARNING
Hazardous Voltage!
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.
Note: For additional information regarding the safe discharge of capacitors, see
PROD-SVB06A-EN or PROD-SVB06A-FR
Disconnect the following power supply and control wires from each VFD.
