Installation
32 AFDH-SVN03H-EN
Electrical Installation (All AFDH
Models)
Important: Route Incoming Power Conduit to the Roof
of AFDH Cabinet! The air-cooled AFDH drive
is designed to have the incoming power
conduit routed vertically into the unit
through the removable conduit connection
cover located on the left-hand rear corner of
the cabinet roof. If the starter that is being
replaced by the AFDH drive has the
incoming power conduit routed
horizontally across the top of the starter, or
connected to the side or to the bottom of the
starter cabinet, an electrician will be
required to reconfigure the conduit and
wiring. Routing the incoming power
conduit into the AFDH cabinet anywhere
other than through the specified location on
the cabinet roof, will be considered an
unsupported field modification to the
cabinet design
Install Shorting Buss Bars (Unit Mount
Only)
Note: Shorting buss bars must be installed since the
AFDH is a three-lead device while the starter was a
six-lead device.
1. Remove the motor terminal lug from all six terminals
on the compressor motor terminal board.
2. Install the three buss bars provided, one each between
the following motor terminal pairs
a. T1 - T6
b.
T2 - T4
c. T3 - T5
3. Reinstall all of the motor terminal lugs.
WARNING
Hazardous Voltage with 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.
WARNING
Conform to All Applicable National, State,
and Local Electrical Codes!
Failure to follow all applicable codes could result in an
arc flash event, electrocution, explosion, or fire, which
could result in death or serious injury. Users MUST
conform to all applicable national, state, and local
electrical codes during the electrical installation and
servicing of this product.
NOTICE:
Use Copper Conductors Only!
Failure to use copper conductors could result in
equipment damage as unit terminals are not designed
to accept other types of conductors.
NOTICE:
Keep Dirt, Debris, or Metal Filings From
Entering the Drive Cabinet!
Failure to observe the appropriate precautions could
result in damage to the electrical components when
they are energized for the first time. Take all
precautions necessary to prevent any dirt, debris, or
metal filings from entering into the drive cabinet during
the installation process.
