Assembling the kit
Start the assembly with the resistors and the diodes. First solder the
components on the solder side of the PCB and then cut the excess
wires with the side cutter as short as possible. Next solder the IC-
socket, the rectifier and the transitors. Continue with the trimm-pot and
the capacitors. Finally solder the relay and the terminal strips.
Caution:
Electrolytic capacitors, transistors, diodes, rectifiers and ICs must be
placed in the right direction! If you solder them the wrong way the affected
parts can be damaged when you connect the power. In the worst case the
whole circuit can be damaged. In any case, a wrongly connected part will
not function.
Performing a visual check
Even if you have a ready-built module you must perform a visual check
that screws, plugs and other fasteners are firm and tight to exclude
transport damage.
Caution:
Do not power up the module yet.
Damaged material and/or incorrect handling of parts can always be a
danger. After assembling the kit, perform a visual inspection.
Remove all loose parts, wire ends or drops of solder from the PCB.
Remove all sharp wire ends.
Check solder spots that are too close to each other for short circuits.
Check that all components are polarised correctly. When you have
taken all these precautions, go on to the next part.
