Installation Electrical
General Recommendations
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.
Hazardous Voltage!
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 can-
not be inadvertently energized. 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.
All wiring must comply with local and National Electric Codes. Minimum circuit ampacities and
other unit electrical data is on the unit nameplate. See the unit order specifications for actual
electrical data. Specific electrical schematics and connection diagrams are shipped with the unit.
Typical wiring diagrams are in the back of this manual.
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of conductors. Failure to use copper con-
ductors may result in equipment damage.
Do not allow conduit to interfere with other components, structural members or equipment. All
conduit must be long enough to allow compressor and starter removal.
Note: To prevent control malfunctions, do not run low voltage wiring (<30V) in conduit with con-
Power Supply Wiring
Model AdaptiR™ with AFD option chillers are designed according to NEC Article 310-15; there-
fore, all power supply wiring must be sized and selected accordingly by the project engineer.
For a complete discussion on the use of conductors, see Trane Engineering Bulletin EB-MSCR-40.
Refer to Trane Engineering Bulletin CTV-EB-93 for power wire sizing.
Water Pump Power Supply
Provide power supply wiring with fused disconnect for both the chilled water and condenser
water pumps.
Electrical Panel Power Supply
Power supply wiring instructions for the starter/control panel are:
4. Run line voltage wiring in conduit to access opening(s) on starter/control panel or pull-box.

ductors carrying more than 30 volts.
See CTV-EB-93 for wire sizing and selection information and refer to
ical electrical connection sizes and locations. Always refer to submittal information for your
actual unit specifications.
