Original Prusa i3 MK3S+ kit assembly 103
STEP 18 Preparing the PSU parts
For the following steps, please prepare:
24V power supply (1x)
Power panic cable (1x)
PSU-cable (2x)
M4x10r screw with dome head (2x)
M3x10 screw (2x)
The PSU is designed to work worldwide and automatically switch to the local
voltage.
The cable terminals (connectors) have a different width, make sure you follow the
instructions. The blue terminals won't fit the Einsy board.
STEP 19 Assembling the PSU
Turn the back of the printer towards you and locate the PSU holders. Insert M3x10
screws into them. Make only 3-4 turns, it should be enough to hold the PSU for
now.
Take the PSU and place it above the screws. Adjust the span of the PSU holders.
Slide the PSU on the screws and tighten them, but not too firmly. We need to
adjust the position in the next steps.
Make sure you can slide with the PSU up and down.
The screws should be able to hold the PSU in a "vertical" position for now.
