6.2. Connection to the voltage supply
When connecting the vehicle´s current collectors check the right
assignment (left / right). When interchanging the connections, the
outputs switched depending on the direction of motion will be switched
incorrectly in regard to the direction of travel.
6.3. Connecting accessories to the outputs
Disconnect any existing diodes in the leads to the lamps, otherwise the
lamps might not light. Connect the lamps and the accessories to the
function outputs of the decoder (AUX1 to AUX3). Observe the maximum
current of the outputs (AUX1, AUX2: 300 mA, AUX3: 100 mA).
When you want to use the factory (default) settings of the decoder,
check the preceding list. Otherwise you can assign the outputs to the
function keys voluntarily by setting the configuration variables.
If the lamp or the accessory is already connected with one side to
vehicle ground, the connection is complete. If not, connect the second
side of the lamp or the accessory to the decoder´s return conductor for
all functions (point X7).
6.4. Connecting LEDs to the function outputs
The decoder´s function outputs switch respective to the decoder
ground. For that reason you must connect the cathodes (-) of the LEDs
to the function outputs and the anodes (+) to the decoder´s common
return conductor for all function outputs (point X7).
Caution:
If you use light-emitting diodes (LEDs) you must always operate them
via a series resistor, otherwise they will be damaged when put into
operation or their duration of life will be reduced considerably!
When doing without a series resistor, other components undertake the
series resistor´s function (e.g. rails, wheels, current connectors),
