Connection to the power supply
Connect the double flashlight according to the figures and the list, to
the power supply. When connecting the PCB to (analogue) a.c. voltage,
the connections´polarity is not relevant. When connecting the PCB to
(analogue) d.c. voltage, you have to observe the connections´ polarity.

Use in non digital D.C. layouts
The LEDs shine in one direction of travel only
when the double flashlight is used in vehicles
run in railway layouts supplied by (analogue)
d.c. voltage. If they should work in both
directions of travel, mount an additional brigde
rectifier (e.g. item no. 83-19100-10, not
included in delivery) according to the figure.
Connection to a decoder output
Connect the connection "GND" to the output of the locomotive or
function decoder you intend to switch the double flashlight. Connect the
connection "12V", "Uin" or "U+/~" to the return conductor of the output
or the return conductor for all outputs.
