POWER GENERATION – DESCRIPTION AND OPERATION
External power source
External 12V DC power can be connected to the airplane on ground through a special socket
on the right side of the airplane (cap 20).
To prevent the connection from being made with inverted polarity, the socket is designed in
such a way that, if incorrectly inserted, the connection to the system does not occur.
When DC external power is connected, the “ external power relay” automatically allows to
feed directly the battery bus.
Before external power is connected, Master Switch must be turned OFF; after connection of
external DC source, Master Switch can be turned in the ON position in order to recharge the
battery.
Voltmeter and Ammeter
The electrical system is equipped with a voltmeter located on the instrument panel, upper
right side; has a range of 8 to 16 Volt.
The battery charge/discharge current can be read on an ammeter located in the instruments
panel, lower right side.
