Electrical Installation (All Afdh Models) - Trane AFDH Installation Instructions Manual

Installation
NOTICE:
Improper Unit Lowering!
Do not drop the drive cabinet assembly onto the
evaporator mounting brackets when setting it into
position! Dropping the cabinet onto the brackets could
result in damage to the drive cabinet, the brackets,
and/or the evaporator shell.
1. The remote-mounted AFDH and harmonic filters are
designed to bolt in place on the floor using the hole
pattern on the bottom of the drive (see the following
figure).
Figure 29. Bolt placement for remote-mounted AFDH
and harmonic filters
2. Prepare lifting equipment and rigging.
a. Depending upon the model type, a unit-mounted
AFDH can weigh up to 1400 pounds. Confirm the
weight of the AFDH unit to be installed. For D-Frame
units refer to Table 5, p.
b. Verify that the intended lifting device and rigging
has the capacity to safely handle the load before
hooking up to the two factory provided lifting points
on top of the cabinet assembly.
c. Use the appropriate rigging techniques to ensure
that the cabinet assembly will be balanced about its
center of gravity during lifting. Refer to
"Recommended Rigging and Lifting Procedures for
AFDH Drive Units," p.
3. Slowly lower the cabinet into place and secure the
drive to the floor at the bottom of the cabinet.

Models)
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.
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
