PSL2 Assembly guide

25. Transformer plate assembly

Attach the transformer plate to the PCB with one M3x10 screw and one self locking nut.

26. Case assembly

Assemble the front plate and the two sides of the case with four black M4 
countersunk screws.
The internal face of the sides is the one with two grooves.

27. Regulators heatsink assembly

Place one and two M3x10 pan head screws with two nuts on the regulator heatsinks. 

Insert the regulator pins into the PCB. Do not solder yet.

28. Top and bottom cover fixing nuts

Add 2 nuts in the top and bottom grooves of both sides of the case (for a total of 8 nuts). They will be 
used to attach top and bottom covers. 

29. PCB insertion

Insert the PCB into position by sliding the heatsink screws into the case grooves. Make sure the LEDs fit 
into the front plat holes.
