WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote
disconnects 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
