TERMINAL CONNECTION DIAGRAMS -
G40 SIIIA LSA42.3
To modify the connection, change the position of the
stator cables on the terminals. The winding code is
specified on the nameplate.
Any intervention on the alternator terminals during
connection or checks should be performed with the
machine stopped.
In no case should the internal connections in the
terminal box be subjected to stresses due to cables
connected by the user.
12 wires connection
Reconnecting impossible for output by cable
(option).
