Cabinet Servicing
For information regarding the servicing of drive
components please refer to the appropriate Rockwell
literature.
Service Information
This equipment should be installed, adjusted and serviced
by qualified electrical maintenance personnel who are
familiar with the construction and operation of the
equipment and the hazards involved, as defined in the
National Electrical Code. Trane assumes no liability for
installation or service procedures performed by
unqualified personnel.
Parts Ordering Information

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.
NOTICE
Do Not Megohm Test!
Failure to follow instructions below could cause
damage to the controller circuitry. Do NOT use a
megger to perform continuity checks in the drive
equipment.
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. If this equipment is
interlocked with other equipment, 115 volts AC may be
present in the cabinet even though the main power is
disconnected. If this is the case, these interlock signals
should be deactivated before any work is performed on
this equipment. Suitable warning tags or disconnects
should be added to these circuits and all circuits should
be tested before attempting to energize or service the
controller.
For additional information regarding the safe discharge
of capacitors, see PROD-SVB06*-EN.
