Introduction
Read this manual thoroughly before operating or servicing
this unit.
Warnings, Cautions, and Notices
Safety advisories appear throughout this manual as
required. Your personal safety and the proper operation of
this machine depend upon the strict observance of these
precautions.
Important Environmental Concerns
Scientific research has shown that certain man-made
chemicals can affect the earth’s naturally occurring
stratospheric ozone layer when released to the
atmosphere. In particular, several of the identified
chemicals that may affect the ozone layer are refrigerants
that contain Chlorine, Fluorine and Carbon (CFCs) and
those containing Hydrogen, Chlorine, Fluorine and
Carbon (HCFCs). Not all refrigerants containing these
compounds have the same potential impact to the
environment. Trane advocates the responsible handling of
all refrigerants-including industry replacements for CFCs
and HCFCs such as saturated or unsaturated HFCs and
HCFCs.
Important Responsible Refrigerant
Practices
Trane believes that responsible refrigerant practices are
important to the environment, our customers, and the air
conditioning industry. All technicians who handle
refrigerants must be certified according to local rules. For
the USA, the Federal Clean Air Act (Section 608) sets forth
the requirements for handling, reclaiming, recovering and
recycling of certain refrigerants and the equipment that is
used in these service procedures. In addition, some states
or municipalities may have additional requirements that
must also be adhered to for responsible management of
refrigerants. Know the applicable laws and follow them.
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.
• Customers are responsible for all field wiring in
compliance with local, national, and/or international
codes.
The three types of advisories are defined as follows:
WARNING Indicates a potentially hazardous
situation which, if not avoided, could
result in death or serious injury.
CAUTIONsIndicates a potentially hazardous
situation which, if not avoided, could
result in minor or moderate injury. It
could also be used to alert against
unsafe practices.
NOTICE Indicates a situation that could result in
equipment or property-damage only
accidents.
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 electrical codes.

Overview
AFDE-SVU02F-EN 11
•Customers are responsible for all field wiring with
respect to EMC and EMI interference. Customers are
responsible for mitigating the risks associated with
EMC and EMI interference that can occur as a result of
customer-provided field wiring as dictated by
international, national, and local codes. This also
implies that customers are responsible for incoming
power wiring to the drive with respect to EMC and EMI
interference.
All customer wiring, including power wiring to drives,
must be separated: 24–27 Vdc, 110–120 Vac, and 380–
600 Vac each must be in separate conduit runs.
The customer is required to provide an overcurrent
protective device upstream of all drives in accordance with
IEC standards and/or any applicable national and local and
codes.
Service personnel must use proper PPE for servicing and
must also use proper lockout/tagout procedures during
servicing: lock the drive disconnect handle before
servicing to prevent accidental pulling of disconnect
handle at the drive panel.
In addition, service personnel should disconnect the main
supply disconnecting device upstream of the drive before
performing any service on any part of the chiller.
AFDE Information
The AFDE refrigerant-cooled Adaptive Frequency Drive is
a pulse width modulated (PWM) design incorporating
both an IGBT (Insulated Gate Bipolar Transistor) active
rectifier and inverter. It is designed for 380–480 volt
application. This drive converts AC power to DC power and
back to AC power. The incoming 380–480 volts are
converted to a constant 700 Vdc by the active rectifier, and
into a section of capacitors that are used to store the DC
voltage. The DC output feeds the inverter IGBTs that switch
at predetermined time to change the DC input voltage to a
symmetrical AC output voltage of desired magnitude and
frequency. The output frequency range is 38 to 60 hertz.
The DC voltage is fixed at 700 Vdc. A variable output is
accomplished by PWM control within the inverter by the
IGBTs which are basically transistors that turn on and off
in response to the gate driver.
A combination of two distinct operating modes make up
the AFDE control within the chiller’s UC800 control. First
by controlling the inlet vanes, and second by modulating
impeller speed from 38 to 60 hertz. The IGBTs control the
speed in response to the UC800 compressor control
signal. Circuit breakers, surge capacitors and ground
faults are standard on all AFDE units.
Some of the basic principles of the drive are:
• Less than or equal to 5 percent current harmonic
distortion (TDD).
• Minimum efficiency of 97 percent at rated load and
60 Hz.
• Unit displacement power factor of 0.98 or better at full
load and a value of 0.96 at part load.
• Low in rush current.
• The current never exceeds the full load amps.
• The AFDE varies the motor speed in response to the
speed command from the UC800 control.
The CenTraVac™ Control Panel has full control of the unit
operation, including the start/stop functions. If you
encounter a fault condition or an alarm on the drive, the
Tracer® AdaptiView™ display will indicate “alarm” and an
“alarm message.”
This manual covers the features and specifications that are
unique to the Trane Adaptive Frequency Drives being
produced for Trane. Only product information is covered
here that supplements that presented in the standard
LiquiFlo instruction manuals that ship with the unit.

Drive and Cabinet
Enclosure Rating
The Trane® cabinet has a NEMA 1 enclosure rating:
NEMA 1: Vented. Intended for general-purpose indoor
applications.
Environmental Conditions
Important: Location of the AFDE is important if proper
performance and normal operating life is to
be expected. Therefore, unless designed for
special environments, the controller should
be installed in an area where the following
conditions exist
• Verify that NEMA 1 enclosure drives can be kept clean
and dry.
• The area chosen should allow the space required for
proper air flow. Adequate clearance for air circulation
around the enclosure is a 6 inch (15.25 cm) minimum
clearance required wherever vents are located in the
cabinet.
• Be sure that the NEMA 1 enclosure is installed away
from oil, coolants, or other airborne contaminants.
• Do not install the drive above 3300 feet (1000 meters)
without derating output power. For every 300 feet
(91.4 meters) above 3300 feet (1000 meters), derate
the output current 1%.
• Line frequency is 50 or 60 Hz.
• Line Voltage is 380–480 volts; variation are within
+10%.
• Non-corrosive location.
• Verify that the drive location will meet the
environmental conditions specified in Table 1.
