Important:
Customers are responsible for all field
wiring in compliance with local, national,
and/or international codes.
Use the following steps to connect AC input power to the
cabinet:
Note:
Graphic labels (shown above) are used for CE
application only.
Important:
•
Before servicing, disconnect all power sources and
allow at least 10 minutes for capacitors to discharge.
•
All electrical enclosures-unit or remote-are IP2X.
1. Turn off, lock out, and tag the input power to the drive.
2. Remove the 12 x 17 in. (30.5 x 4 cm) panel from the top
left of the drive enclosure.
3. Once removed, drill the wire routing holes in the panel.
These wire routing holes are the only entry points for
input power wiring into the cabinet.
4. Install the appropriate conduit hubs.
5. Reinstall the cabinet’s top panel.
6. Connect the three-phase 380–480Vac input power
leads:
a.
For non-CE units
, connect the input power leads to
circuit breaker terminals L1, L2, and L3.

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 an appropriate voltmeter that all
capacitors have discharged.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN.
NOTICE
Load Side Wiring!
Failure to route the wires through the cores could result
in bearing damage. The electrical wiring from the drive
output to the motor must be routed through the
magnetic cores. The cores are used to protect the
motor bearings.
NOTICE
Equipment Failure!
Failure to follow instructions below could result in
damaged equipment. Do not cut holes in adaptive
frequency drive enclosure. Debris falling inside of
adaptive frequency drive could cause failure of
electronic components.
