Connecting the rotor cables
Note: The cabling from all converter modules must be physically identical considering
cable type, cross-sectional area and length. When connecting several cables per phase, it
is recommended to divide the cables as evenly as possible among the modules.

Connection diagram
A connection diagram of frame 2×R8i parallel connected power modules feeding one
generator is shown below. The cable connection for frames 2×R8i and up is similar.
Note: Rotor-side cable connection terminals are U2, V2, W2 and PE. To be wired by the
user. For selection of the cables, see chapter Planning the electrical installation . For the
terminal sizes, tightening torques and lead-throughs, see chapter Technical data .
Note: Depending on the type of the generator used, the phase order may vary.
