6.4. Assembly
Proceed according to the order given in the list below. First solder the
components on the solder side of the PCB and then cut the excess
wires with the side cutter. Follow the instructions on soldering in
section 3.
Caution:
!
Several components have to be mounted according to their polarity.
When soldering these components the wrong way round, they 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.

Mounting orientation of no importance.
Observe the polarity!
The negative end of the diodes is marked with
a ring. This is shown in the PCB layout.
Mounting orientation of no importance.
Mount the sockets that way, the marking on
the sockets shows in the same direction as
the markings on the PCB board.
Observe the polarity!
The pin connections are printed on the
housing. The longer connecting pin is the
positive pole.
The mounting orientation is preset by the
layout of the three pins.
