Medium-Voltage Starter Types (2,300–6,600 Volts)
The AFD is designed for a maximum operating temperature of 104°F . However, optimal operation
and design life will be experienced if the ambient temperatures are kept well below this maximum.
The maximum AFD heat rejection is listed on the AFD submittal drawing in this package. Additional
equipment room cooling provisions may be required.
For all remote medium voltage AFDs, note that 4 kVA at 120-volt control power must be provided
to the chiller control panel, and this is customer supplied. Refer to the wiring diagrams in the
submittal package.
On some larger Frame B AFDs, note that the AFD itself requires a separate 8 kVA at 480-volt power
supply.This is in addition to the main power supply voltage.
Installation Notes
The AFD ships as a single enclosure, except for some "top hat" enclosures.These top hat sections
must be field installed. Refer to the AFD drawings for more information.
It is suggested that the AFD be placed on a housekeeping pad; anchoring the AFD to the ground
is not a manufacturer's requirement. Consult local codes.
Refer to the AFD installation, operation, and maintenance manual, AFDJ-SVU01A-EN (Installation,
Operation, and Maintenance: Remote-Mounted Medium Voltage Air-Cooled Adaptive Frequency
Drive withTracer AdaptiView Control), or the most recent revision, for more detailed information
on AFD installation, operation and maintenance requirements.
Dimensions
See the specific submittals for the application. In general, for the the 4,160-volt class, the geometry
is as follows for the two frame sizes:
A Frame.
94" wide X 40" deep X 105" high
B Frame.
182" wide X 40" deep X 105" high

Harmonic currents on the line side—Harmonics are minimized through the use of a common
mode choke and active rectifier.The AFD will meet a current harmonic distortion level of
5 percent or less in total demand distortionTDD as measured at the input to the AFD.
