The external power receptacle is attached left under the rear seat.
The main-relais is located at the left side of the firewall, above the starter-relais. For the
avoidance of sparks, this relais does not switch before a safe contact from plug to recepta-
cle will be ensured. During the engine start, the master switch has to be switched in "OFF"-
position for the disconnection of the battery from the aircraft electric circuit.
