Installation - Electrical

Installer-Supplied Components

Customer wiring interface connections are shown in the
electrical schematics and connection diagrams that are
shipped with the unit.The installer must provide the
following components if not ordered with the unit:
• Power supply wiring (in conduit) for all field-wired
connections.
• All control (interconnecting) wiring (in conduit) for
field supplied devices.
• Fused-disconnect switches or circuit breakers.
• Power factor correction capacitors. (optional)

Power Supply Wiring

All power supply wiring must be sized and selected
accordingly by the project engineer in accordance with
NECTable 310-16.
WARNING
Proper Field Wiring and Grounding
Required!
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 electrical codes. Failure to
follow code could result in death or serious injury.
WARNING
Hazardous Voltage w/Capacitors!
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 an appropriate voltmeter that all
capacitors have discharged. Failure to disconnect power
and discharge capacitors before servicing could result in
death or serious injury.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06A-EN
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.
RTAC-SVX01J-EN
The type and installation location(s) of the fused
disconnects must comply with all applicable codes.
NOTICE:
Use Copper Conductors Only!
Unit terminals are not designed to accept other types
of conductors. Failure to use copper conductors could
result in equipment damage.
Cut holes into the sides of the control panel for the
appropriately-sized power wiring conduits.The wiring is
passed through these conduits and connected to the
terminal blocks, optional unit-mounted disconnects, or
HACR type breakers. Refer to
To provide proper phasing of 3-phase input, make
connections as shown in field wiring diagrams and as
stated on the WARNING label in the starter panel. For
additional information on proper phasing, refer to "Unit
Voltage Phasing. " Proper equipment ground must be
provided to each ground connection in the panel (one for
each customer-supplied conductor per phase).
115 volt field-provided connections (either control or
power) are made through knockouts on the lower left side
of the panel (Figure 28, p.
required for each 115 volt power supply to the unit. Green
lugs are provided for 115V customer wiring.
Single Point Power on Dual Panel Units
(Optional)
Units which require two control panels and with single
point power option selected, are built with a power
connection junction box located in the center of the unit as
shown in Figure 29, p. 86. Customer will connect to
terminal blocks inside this panel.
