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
Proper Field Wiring and Grounding Required!
All field wiring MUST be performed by qualified personnel. Improperly installed and grounded
field wiring poses FIRE and ELECTROCUTION hazards. To avoid these hazards, you MUST follow
requirements for field wiring installation and grounding as described in NEC and your local/
state electrical codes. Failure to follow codes could result in death or serious injury.
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
could 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
