Kit Assembly
In the area of the digital inputs are standing much resistors in direct environment and
make it difficult to put the diodes through the holes. You can pull the wires down from the
bottom side or push them from up with a screwdriver.
The LM4040-diode has a special structural shape (TO92-housing). For preparation the pin
in the middle has to be bend about 1-2 mm back (in direction of the round housing part),
like it is shown in figure 42.
The next step is to mount the LM4040-diode. Then bend the connection wires on the
bottom side and solder them.
