Pre-Installation

Confirming the AFDH Package can
be Properly Installed
This chapter details potential interference fit problems,
mechanical incompatibility situations, electrical code
stipulations, and electrical conduit and wiring issues that
can prevent the successful installation and/or operation of
an AFDH upgrade drive package.
Installation Considerations for Unit-
Mounted AFDH Drives
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.
Evaluate Space Available for Rigging/
Installing Unit-mounted AFDH
All models of the E-Frame AFDH unit-mounted upgrade
drives are taller, wider, and deeper than the typical Wye
Delta unit-mounted starter they are intended to replace.
Accordingly any project should start with a careful
evaluation on whether there is ample enough space to rig
the AFDH into place and if any of the existing building
piping and conduit will not interfere with its mounting.
