1. INTRODUCTION
The DC/DC application creates output according to the needs of the system, and it is possible to
integrate into the system with different topologies. Choosing applicable topology, see the Design
Guide, Hybridization (DPD01887A).

For more detailed parameter information, see Chapter 2 "Parameters".
1.2 Connection
Connect the phase cables (U, V and W) and cable B-/DC- to correct terminals. See Figure 2, “FR4FR9 main terminals,” on page 3, Figure 3, “CH62 main terminals,” on page 4, Figure 4, “FI4-FI10
basic wiring diagrams,” on page 5 and Figure 5, “2 x FI10 basic wiring diagram,” on page 6.

NOTE: The connection varies according to drive. Always check the connection terminals from the
instruction manual of the drive in question. E.g. in FR4-FR6 INU devices (FI4-FI6) B- = DC-.
