Annex 16 Replacing the Excitation Battery
28V-Version
1. Disconnect the excitation batteries (b).
2. Remove the upper excitation battery holder (a). To do this,
undo the two screws (c).
3. Replace the excitation batteries (b).
4. Fit the upper excitation battery holder to the lower excitation
battery holder using two screws (c) and two washers (d).
Tightening torque:
3.5 Nm
5. Connect the wiring harness to the excitation batteries. The
blue cable lug is pushed onto the black connection (-) of the
first excitation battery. The short connection line connects
both excitation batteries (series connection). The red cable
lug is pushed onto the red connection (+) of the second
excitation battery. Afterwards, connect the wiring harness to
the wiring harness of the alternator regulator (“Exc. Batt“
plug connection).
CAUTION: Never connect a voltage to the alternator when the lines to the
excitation battery are not connected. The line to the excitation
battery carries a voltage from the alternator and must therefore
not come into contact with a ground connection or similar.
Note: The place where the excitation battery is installed depends on
the aircraft installation.
