Assembling the kit
Start the assembly with the resistors and the diodes. First solder the
components on the solder side of the PCB and then cut the excess
wires with the side cutters, as short as possible. Continue the assembly
with the electrolytic capacitors and the transistors.
!
Caution:
Diodes, electrolytic capacitors and transistors must be placed in the
right direction! If you solder them the wrong way the affected parts can
be damaged when you connect the power. In the worst case the whole
circuit can be damaged. At the best, a wrongly connected part will not
function.
Finally solder the terminal strips. Join them together before soldering.
Performing a visual check
Perform a visual check after the assembly of the module and remove
faults if necessary:
§
Remove all loose parts, wire ends or drops of solder from the PCB.
Remove all sharp wire ends.
§
Check that solder contacts which are close to each other are not
unintentionally connected to each other. Risk of short circuit!
§
Check that all components are polarised correctly.
When you have remedied all faults, go on to the next part.

Connecting the light signal switch

The Maerklin* Hobby-light signals have two blue and one red
connecting wire with a connector. Break off the connector, you won't
need it. In case you want to install an additional train synchronisation
you can use the red wire again.
Then make the connections according to the following list and the
connecting diagram (Fig. 3).
