Terminal strips
Terminal strips are solder-in screw-type terminals. They provide a
solder-free and safe connection of the cables to the circuit, which can
still be seperated any time. When several terminal strips have to be
mounted side by side, they have to be put together before mounting.
Assembling the kit
Note: The components R6 and JP1 shown on the layout, are not
required for this application and thus do not need to be inserted.
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 cutters, as short as possible.
Then insert and solder in the IC-sockets. The sockets must be mounted
according to the marking on the PCB.
Continue the assembly with the relay, the capacitors, the transistors
and the electrolytic capacitors. Then solder in the rectifier, the voltage
regulator, the trimmers and the LED.
!
Caution:
Relays, diodes, ICs, transistors, electrolytic capacitors, rectifiers, voltage
regulators, trimmer and the LEDs must be inserted 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. At the best, a wrongly connected part will not
function.
Next solder the terminal strips. Join them together before soldering.
Finally, insert the ICs 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.
