CP4500 Assembly guide

Safety warning

The kits are main powered and use potentially lethal voltages. Under no circumstance should someone undertake the 
realisation of a kit unless he has full knowledge about safely handling main powered devices.

Please read the “DIY guide” before beginning.
Print or open the following documents :
• CP4500 Schematics

• CP4500 Components layout
• CP4500 Parts list

• CP4500 Setup guide

Follow this guide from item number 1 till the end, in this order. The assembly order is based on components height, from 
low to high profile, in order to ease the soldering process : The component you are soldering is always taller than the 
previously assembled ones and it is pressing nicely against the work area foam.

Soldering

All the PCB holes are metallized. It means the connection between the top and bottom pads is already 

done. The parts must be soldered only from below (unless differently stated).

Use only small diameter solder, 0.5 or 0.7 mm, 1mm maximum. Use just the minimum necessary amount 
of solder. Bad joints are often masked by too much solder.

Cut the component leads and pins totally flush with the PCB after soldering. A too long tail could create 
an electric connection with the side plate.

Here are two excellent introduction to soldering videos:

CP4500 Assembly guide – PCB A

1. PCB to PCB connector CN1A & 

CN2A

Insert the female 2x10 connector into 
the male part and position the later below 

PCB-A 

on the solder side

. The female 

connectors must sit flat on its side. 

Solder two pins, check position then 
solder the other pins.
Do the same for CN2A 2x5 connector.

After soldering remove the female parts.
