Assembly

This instruction will guide you through the steps to be taken. Below some chapters you find some information about the variants. It always starts with Variant:. There you find the components that also needs to be solderd to the PCB for your variant. And if you are not sure about the name of a part, just look into the BOM.

1. level shifter and passive low profile elements

• At first solder the level shifter (LV1)
• Make sure you solder it the right way (you can orientate on the notch of the level shifter)

• Now solder resistor R3

• And now the diodes D1 and D2

• Make sure you put it the right way (you can orientate on template on the pcb)

• Solder the capacitor C1

Variant:

2. R7
   
3. R5, R6 and R7
   
4. R1, R2, C4 and C5

2. PTC fuse, headers and power led

• First solder the PTC fuse (F2)

• Now solder the fuse holder (F1)

• And now the two headers H1 and H2

• Optionally: Solder the power led

3. transistor, electrolytic capacitors, buck power converter and sensor

• Solder the transistor Q1 (put it like the template on the pcb)

• And now the capacitors C6 and C2 (pay attention at + and -)

Variant:

4. PS1

4. relay, terminal blocks

• Solder relay to PCB (K1)

• Finally solder the screw terminal blocks X1 and X2

5. add solder to traces

Add good amount of solder to traces shown in red. For more Amps to flow through.
