Installation Electrical
RTHD-SVX01K-EN 41
Power Supply Wiring All power supply wiring must be sized and selected
accordingly by the project engineer in accordance with
NEC Table 310-16.
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 fused
disconnect switches.
The type and installation location(s) of the fused
disconnects must comply with all applicable codes.
See Figure 19 for electrical installation panel locations.
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.
NOTICE
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as the equipment was not
designed or qualified to accept other types of
conductors.
