general
information
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.
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to
accept other type conductors. Failure
to use copper conductors may result
in equipment damage.
