Power Supply Wiring
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.
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.
All power supply wiring must be sized and selected
accordingly by the project engineer in accordance with
NEC Table 310.15(B)(16).
All wiring must comply with local codes and the National
Electrical Code. The installing (or electrical) contractor
must provide and install the system interconnecting wiring,
as well as the power supply wiring. It must be properly
sized and equipped with the appropriate overcurrent
protection device.
The type and installation location(s) of the overcurrent
protection devices must comply with all applicable codes.
Incoming customer power location varies with unit
configurations. See figures below.
For 150 to 330 ton units:
• Control Panel
– Standard length units (model number digits 9 = C,
D, E, G, H or 44 = X)
– Units with optional harmonic filtration (model
number digit 44 = L)
• Transformer: 200, 230, 380, 400, or 575 V units with
transformer (model number digit 9 = A, B, C, D, or F)
