General Recommendations
As you review this manual, keep in mind that:
• All field-installed wiring must conform to National
Electric Code (NEC) guidelines, and any applicable
state and local codes. Be sure to satisfy proper
equipment grounding requirements per NEC.
• Compressor motor and unit electrical data is listed on
the chiller nameplate.
• All field-installed wiring must be checked for proper
terminations, and for possible shorts or grounds.
• For proper electrical component operation, do not
locate the unit in areas exposed to dust, dirt, corrosive
fumes, or excessive humidity. If any of these conditions
exist, corrective action must be taken.
Notes:
• Always refer to wiring diagrams shipped with
chiller or unit submittal for specific electrical
schematic and connection information.
• All conduit must be long enough to allow
compressor and starter removal.
WARNING
Proper Field Wiring and Grounding
Required!
Failure to follow code could result in death or serious
injury.
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/national
electrical codes.
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.
Important: Do not allow conduit to interfere with other
components, structural members or
equipment. Control voltage (115V) wiring in
conduit must be separate from conduit
carrying low voltage (<30V) wiring. To prevent
control malfunctions, do not run low voltage
wiring (<30 V) in conduit with conductors
carrying more than 30 volts.

component sizing should be based on actual jobsite
operating conditions. This factor can be obtained through
the use of TOPSS™.
