RTAA-SVX01A-EN 49
Installation — Electrical
General Recommendations
All wiring must comply with local and National Electric Codes. Minimum
circuit capacities and other unit electrical data is on the unit nameplate. See
the unit order specifications for actual electrical data. Electrical schematics
are shipped with the unit.
Typical wiring diagrams are in the back of this manual.
WARNING
Hazardous Voltage w/Capacitors!
Disconnect all electric power, including remote disconnects
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 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 PROD-SVB06A-EN or PROD-SVB06A-FR
CAUTION
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.
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.
Caution: To prevent control malfunctions, do not run low voltage wiring
(<30V) in conduit with conductors carrying more than 30 volts.
