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.
