The common positive pole for outputs 1 – 8 and 9 - 16 are the black and white
cables. It is also possible to connect the load directly to the positive pole of the
battery.

The switched voltage at the outputs (with 100% intensity) is always as high, as the
supply voltage of the USM-RC-3. For example if the module is supplied with 12V,
only lamps with 12V should be connected.
If you want to connect LEDs, series resistors are always required. Furthermore,
attention must be paid to the correct polarity of the LED. The series resistors for the
LED’s are depended on the supply voltage, the LED-color and the LED-current.
The table below shows the resistance values required for standard LEDs (approx. 15
mA current):
