Introduction:
You have purchased a kit for your model railway supplied within the assortment of
L
ittfinski
D
aten
T
echnik (
LDT
). These kits are of high quality and easy to assemble.
We are wishing you having a good time for assembling and application of this
product!
General:
Tools required for the assembly
Please assure that the following tools are available:
•
a small side cutter
•
a mini soldering iron with a small tip
•
solder tin (if possible 0.5mm diameter)
Safety Instructions
•
All electrical and electronic components included in this kit shall be used on low voltage
only by using a tested and approved voltage transducer (transformer). All components
are sensitive to heat. During soldering the heat shall be applied for a very short period
only.
•
The soldering iron develops a heat up to 400°C. Please keep continual attention to this
tool. Keep sufficient distance to combustible material. Use a heat resistant pad for this
work.
•
This kit contains small parts which can possibly be swallowed from children. Children
(especially under 3 years) shall not participate on the assembly without supervision.

Set-Up:
For the board assembly please follow exact the sequence of the above
assembly list
.
Cross each line off as
done
after completing the insertion and the soldering of the
respective part.
For the
diodes
please keep special attention the correct polarity (marked line for the
cathode).
With reason to different makes of
electrolytic capacitors
you will find different markings
of the polarity. Some are marked with "+" and some are marked with "-". Each capacitor
has to be assembled to the board that the marking on the capacitor is in correspondence
with the marking on the pc-board.
For
tantalum capacitors
please attend to the
connection wire
marked "+". This wire has
to correspond to the printed mark on the pc-board.
