Panel mount PowerFlex 400 drives, 15HP and larger @ 200-240VAC and 380-480VAC, are supplied with an internal DC link reactor. 7.5-10HP ratings are not supplied with an internal DC link reactor and do not require one for basic operation. The DC bus is accessible for all PowerFlex 400 drives via the P1and P2 terminals. These terminals ship from the manufacturing facility with a jumper bar installed. This jumper bar can be removed and an external DC link reactor wired in if additional inductance is desired. Flange mount PowerFlex 400 drives do not contain a DC link reactor. An external bus inductor is required for 15-20HP @ 380-480VAC flange mount units.
