Assembling the kit
Caution:
Diodes, transistors, Ics and opto couplers should be inserted in the
right direction! If you solder them the wrong way around the affected
parts 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.
Start the assembly with the resistors. First solder the components on
the solder side of the PCB and then cut the excess wires with the side
cutter.
Then insert the four wire bridges Br1 to Br4. Use the off-cut wires of
the resistors.
Next solder in the IC-sockets. They have to be mounted according to
the marking on the PCB.
Continue the assembly with the transistor, the diodes and the terminal
strips. Put together the terminal strips before mounting them.
Finally, insert the opto couplers into the soldered IC-sockets.
Caution:
Do not touch the ICs without first discharging yourself by touching a
radiator or other grounded metal parts. Do not bend the "legs" of the
ICs when inserting them into the sockets. Check that the markings
on the PCB, the socket and the IC show to the same direction.
