In order to ensure the normal operation of the unit electrical components, do not place the unit in
dust, corrosive gas or high humidity environment. If these situations exist, corrective measures
must be taken.
Hazardous Voltage!
Disconnect all electrical power, including remote disconnects before servicing. Follow proper
lockout / tagout (LOTO) procedures to ensure the power cannot be inadvertently energized.
Failure to disconnect power before servicing could result in death or serious injury.
All wiring must comply with local codes. The installation (electrical) contractor must provide and
install system interlock wiring and power wiring. Specific electrical wiring diagrams are in Trane
wiring diagrams.
Use Copper Conductors Only!
Unit terminals are not designed to accept other types of conductors. Failure to use copper
conductors may result in equipment damage.
Do not allow conduits, cables, and wires to interfere with other components, structural members,
or equipment. All conduits, cables and wires must have sufficient length to fit the location
adjustment of compressors and starters. Refer to below table for the recommended wire sizes.
