Routing Of Control Wiring To Afdh Cabinet - Trane AFDH Installation Instructions Manual

Notes:
• The field will have to provide the properly sized ground
wire based on NEC to bond the filter enclosure.
• Power connections should be re-torqued after the first
three to six months of operation and on an annual
basis thereafter.
In addition to power wiring, the harmonic filter has an
internal over temperature switch. This switch must be
wired in series with the high pressure cutout switch. This
will prevent overheating and equipment failure. Refer to
the following figure.

Routing of Control Wiring to
AFDH Cabinet
NOTICE:
Route Incoming Power Conduit to the
Roof of the AFDH Cabinet!
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.
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.
