Terminal 3
Terminal 1 enables to supply the EMS with an external power source (e.g. in case the in-
ternal power supply fails supplying the EMS). Terminal 2 enables powering the EMS dur-
ing engine start (until the engine speed is high enough that the internal generator is able
to supply the EMS). Terminal 3 can be used for supplying the Airframe with electrical en-
ergy after generator A has taken over powering the EMS.
