which holes of the plug-in board, the components have to be
plugged.
Fit the components onto the plug-in board using small flat-
nose pliers. Carefully insert the wires from the top. The cor-
rect position of the connections is important.
When installing LEDs, it is important to note
the mounting direction. The shorter wire is the
negative pole (the cathode K); the longer wire
is the positive pole (the anode A). The larger
holder for the LED crystal is visible from the
cathode side. The K-connector also has a small
flattened area on the casing. This is also the
case with coloured LEDs. The white LED also has a yellowish
fluorescent colour that covers the LED crystal. There are LEDs
that look almost identical from the outside. But looking
through the lens from the front helps to recognise the white
LED even when it is off.
