Pre-Installation
Installation considerations for stand-mounted AFDH
NOTICE:
Stand-mounted AFDH supported by equipment room floor!
A stand-mounted version of an AFDH drive is designed to be rigidly supported by the equipment
room floor. Therefore, a stand-mounted AFDH drive is not recommended for use with a chiller
that is equipped with spring-type vibration or seismic isolators. Trane recommends using a
remote floor-mounted AFDH drive in this application. Trane assumes no responsibility for
equipment damage caused by the installation of an AFDH drive version that is specified as being
incorrect for the application.
NOTICE:
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.
Important: Other factors that affect the space required to successfully install a stand-mounted
AFDH drive include the clearance distances specified by the local electrical codes.
Typical code regulations require an average of 36-inches clearance from the panel
to nonconducting surfaces and 47-inches to a conducting surface. Check and confirm
that when installed, the drive clearances will conform to all local codes. Do not forget
to account for cabinet door swing clearances.
Important: The design intention of a stand-mounted AFDH drive, is for the drive to be installed
in front of the chiller with the motor terminal access cover of the drive cabinet lined
up with the compressor motor terminal box. The cable connections between the
drive and the motor terminals will be shrouded by an extended sheet-metal
transition cover. Refer to
Figure 4 .
Note: Refer to the manual section “AFDH Drive Package Specifications,” p. 22 for the dimensions
and weights of all models of AFDH drives”
