Installation - Electrical

Hazardous Voltage w/ Capacitors!
Disconnect all electric power, including remote disconnects before servicing. Follow
proper lockout/tagout procedures to ensure the equipment 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-
CAUTION
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of conductors. Use of aluminum
or other type of wiring may result in galvanic corrosion or overheating. Failure to use
copper conductors may result in equipment damage.
If the unit does not include a factory-mounted starter, wiring to the unit fan motor must
be provided by the installer and must comply with all national and local electrical codes.
The installer must also furnish a service disconnect switch in compliance with national
and local electrical codes.
Fan motors require motor overload protective devices that are rated or selected in
compliance with the National Electric Code (NEC) or Canadian Electric Code. Specific unit
and motor connection diagrams are provided on the starter/VFD if Trane-provided, or
refer to the motor nameplate.
If wiring directly to the motor, a flexible connection at the motor to permit fan belt
adjustment should be provided. Fractional horsepower motors may be factory
connected to a terminal box on the unit. If this construction is provided, the installer
should complete field wiring to this connection box. For a typical high voltage wiring
schematic, see
