Excitation Output
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.
Refer to the redundancy wiring diagrams on pages 31 … 32 .
Control Power
The 24V DC control power inputs are on TB4 and are labeled BAT(+) and
BAT(-).
