WARNING
Hazardous Voltage w/ Capacitors!
Failure to disconnect power and discharge capacitors
before servicing could result in death or serious injury.
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.
For additional information regarding the safe discharge of
capacitors, see PROD-SVB06* -EN
WARNING
Personal Protective Equipment (PPE)
Required!
Failure to follow proper handling guidelines could
result in death or serious injury. Always wear
appropriate personal protective equipment in
accordance with applicable regulations and/ or
standards to guard against potential electrical shock
and flash hazards.
WARNING
Live Electrical Components!
Failure to follow all electrical safety precautions when
exposed to live electrical components could result in
death or serious injury. 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.
