About the PowerFlex 700AFE
Bus Supply
The PowerFlex 700AFE, catalog code 20Y…, is available in two different power
rating frame sizes (frames 10 and 13) and three different packaging methods:
• IP00 open
• IP21 Rittal
• IP20 2500 Motor Control Centers (MCCs)
Custom enclosures and hardware configurations using Bulletin 2100 MCC
enclosures were created by Rockwell Automation drive systems and many
system integrators. Because of the many variations that are possible with IP00
open type equipment, this document does not cover custom engineered AFE
migrations. Contact an Authorized Rockwell Automation Distributor
specialist, Solution Partner, Recognized System Integrator, or a Rockwell
Automation account manager to discuss engineered solutions for these AFE
migrations.

It was possible to parallel individual converters to increase the total available
DC bus power rating.
• The IP21 Rittal enclosed AFE can have up to six units of either frame
size paralleled.
• The IP20 2500 MCC could have two units of the same frame size
paralleled. Paralleling rules are in place, due to the ampere rating of the
DC bus bars available for the enclosures indicated.
When paralleled, the individual converters operate independently with 5%
droop, so a master/slave architecture was not required. Paralleling required
derating the AFE DC current and power output to 95% of published ratings.
