7. Rectifier Observe the polarity! The pin connections are
printed on the housing. The longer connecting
pin is the positive pole.
8. Electrolytic
capacitors
Observe the polarity! One of the two leads
(the shorter one) is marked with a minus sign.
9. Voltage regulator Observe the polarity!
The cross section of voltage regulators in
SOT-packages is shown in the PCB layout.
With voltage regulators in TO-packages the
unlabelled back side is marked in the PCB
layout by a thick line.
10. Trimm-
potentiometers
The mounting orientation is preset by the
layout of the three pins.
11. Light emitting
diode (LED)
Observe the polarity!
With wired LEDs the longer lead is always the
anode (positive pole).
12. Terminal strips Put together the terminal strips before
mounting them.
13. ICs and
optocouplers in
DIL-housing
Insert the ICs into the soldered socket.
Do not touch the ICs without first discharging
yourself by touching a radiator or other
grounded metal parts.
Do not bend the "legs" when inserting them
into the sockets. Check that the markings on
the PCB, the socket and the IC show to the
same direction.
