Voltage supply. With d.c. voltage: plus pole
Anode (+) of the LEDs
LED- Cathode (-) of the LEDs
Connection to (analogue) a.c. voltage
When connecting the PCB to (analogue) a.c. voltage, the connections´
polarity is not relevant. The LEDs light independently of the direction of
travel. Connect the diode D2 (included in the package) in series to the
LEDs. Otherwise the LEDs are possibly damaged after a short operating
time.
Connection to (analogue) d.c. voltage
When connecting the PCB to (analogue) d.c. voltage, you have to
observe the connections´ polarity. Connect the connecting point "GND"
to the minus pole and the connecting point "VCC" to the positive pole
of the voltage supply. .
The LEDs light in one direction of travel only when connected to
(analogue) d.c. voltage. If they have to work in both directions of
