Sound module USM-RC-2
General references to the wiring in the model:
You should use cables with a core diameter of at least 0,75mm² for the connection of
the power supply. For all other connections you can use smaller cables such as
0,25mm².
Unfortunately the speed controllers and motors in the model are often strong
interference sources, which could disturb the electronic of the sound module or the
sound output (whistles, humming in the loudspeaker). Therefore all motors should be
absolutely interference-suppressed!
It is also important to pay attention, to best possible „clean" wire routing. You should
use always short wires and avoid any unnecessary loops. The wires for the supply
voltage of the sound module should be connected to the driving-battery as direct as
possible.
A separate installation of interfering cables (for example motor cables), can achieve
significant improvements.
Nevertheless, if you still have interferences made by a drive controller, you should
connect an electrolytic capacitor (for example 1000µF or bigger) close to the positive
pole at the drive controller and at the sound module.
