The excitation outputs are on TB2 and are labeled EXC(+) and EXC(-).
Twisted, shielded cabling is required for the excitation outputs.
Figure 7 - Excitation Output Connections, Non-redundant CGCM
When the redundancy function is used, three or four external flyback diodes in
series must be placed across the generator field winding.
See the redundancy wiring diagrams on pages
