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.
Note: For additional information
regarding the safe discharge of
capacitors, see PROD-SVB06A-EN or
PROD-SVB06A-FR
