Comparison
This section describes cooling and airflow requirements for the PowerFlex
700AFE and PowerFlex 755TM bus supplies. Compare the requirements for
the existing bus supply to the equivalent PowerFlex 755TM bus supply to
confirm the location can support the requirements of the migration solution.
PowerFlex 700AFE Installation Requirements
See the PowerFlex 700AFE user manual, publication 20Y-UM001, for detailed
