WARNING
Live Electrical Components!
During installation, testing, servicing,
and troubleshooting this equipment, it
may be necessary to work with live
electrical components. Have a
qualified licensed electrician or other
individual who is properly trained in
handling live electrical components
perform these tasks. Failure to follow
all electrical components could result
in death or serious injury.
WARNING
Hazardous Voltage w/Capacitors!
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.
