Zone Sensor Installation

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 a
CAT III or IV voltmeter rated per NFPA 70E that all
capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN.".
