12 V / 24 V DC POWER CONNECTION
While the standard AE 6490 version is designed for 12 V (with allowed variations
between 10.8 and 15.6 V) standard car installation (with negative ground) the AE 6491
version can operate under both voltage systems 12 or 24 V (up to 28 V variations). So
the 24 V version can be used in Trucks or boats which only have 24 V power supply. A
switching is not necessary, the radio detects 12 or 24 V systems automatically.
DC cable wiring
Connect the negative (black) DC power lead to the vehicle chassis or directly
to the vehicle battery negative terminal if preferred.
Connect the positive (red) DC power lead via the in line fuse to a suitable point
in the vehicle fuse box or directly to the positive battery terminal.
It is as well possible to connect the radio to a switched DC network section to
allow automatic on-off with the ignition switch, because the radio stores all
last used settings
It may be necessary in some special cases to use a line filter against alternator
noise. This is depending on the position in the car electrical supply system
where you have connected your radio with + and -. If difficulties appear, we
recommend to test other connecting methods in the car installation as well.
