Caution!
Depending upon their make the electrolytic capacitors show different polarity
markings. Some manufacturers mark “+”, others “-“. The polarity specification
printed by the manufacturer on the electrolytic capacitor is important.

1.4 IC-sockets
Insert the sockets for the integrated circuits (ICs) as well as for the LED-displays in the
corresponding positions on the assembly side of the printed circuit board.
corresponding positions on the assembly side of the printed circuit board.
Caution!
Pay attention to the indentation or any other such marking on the front side of the
socket. This is the marking (connection 1) for the ICs that are to be used later. The
sockets must be inserted in such a way that this marking matches the marking at
the printed side of the board!

In order to prevent the sockets from falling out when the printed circuit board is turned
over (for soldering), every two pins of the socket lying diagonally opposite to each other
are bent and thereafter all the contact pins are soldered.

1.5 Soldering
pins
Press the soldering pins (for connecting the operating voltage and sensor) with the help
of flat-nose pliers from the assembly side in the holes marked accordingly. Thereafter,
the pins are soldered on the side with the conducting pathways.
