⬢Place the printer so that you have easy access to the bottom side of the PSU.

⬢Remove the left screw on the PSU circuit board. Note there is a washer on the screw.  Do not throw the screw away, you will need it later.

⬢Place the single end of the PE (not the forked end) cable into the same place you have removed the screw. Secure the cable by re-using the screw together with the washer.

⬢Guide the PE cable so that it does not interfere with the threaded column under the PE connector.

In the following steps, we will be connecting the power cables one by one. The terminal screws are installed on the PSU already. Loosen them but don't remove them completely so they don't get mixed up with the other type of screws used on the xBuddy board side of the cable. Each of the two power cables has two leads.
One has a prevailing red color = positive / + 
One has a prevailing black color = negative / -

⬢Note that the power cables have different connectors on each end. For now, prepare the U-shaped connectors (crimping tube color may vary).

The red cable (positive) may have a black stripe on it. Similarly, the black cable (negative) can have a red stripe on it.

⬢Take two RED wires and slide the fork connectors all the way into the first two (positive) terminals from the left on the bottom of the PSU. Make sure the steel washer is above the "fork" connector.

⬢Tighten the terminal screw firmly.

Keep in mind some parts are made out of plastic. When tightening each of the terminal screws, proceed carefully.

⬢Take the BLACK wires and slide them all the way into the last two (negative) terminals. Make sure the steel washer is above the "fork" connector.

⬢Tighten the terminal screw firmly.

⬢Connect the power panic cable into the PSU. Use the side with the black connector at the end.

⬢Place the psu cover over the power terminals. Make sure the "PRUSA" logo is facing upwards.

⬢Take a look from the bottom of the PSU and guide all the PSU cables through the cable clips according to the picture.

⬢Slide the zip tie through the circular holes in the frame to create a loop on both sides of the frame so that the cable goes through both loops.

⬢Start tightening the zip tie so it is snug and holds the wires on both sides.

⬢Cut off the remaining part of the zip tie very carefully.

⬢Continue guiding the cables toward the xBuddy. Include the Y motor cable into the bundle.

⬢Secure it with another zip tie to the frame.

⬢Carefully guide and fold the xLCD cable under the cable bundle. Do not include the xLCD cable in the cable bundle. Guide it under the cable bundle and leave it free for now.

⬢M3w washer (1x)

⬢M3x6 screw (1x)

⬢M4x5 screw (1x)

⬢M3nEs nut (1x)

⬢Zip tie (5x)

The following steps are taken from another printer upgrade guide. Therefore, parts such as the Y-carriage are missing. However, this does not have any effect on the silver PSU connection process.

⬢From the inner PSU side of the short extrusion, insert the M3nEs nut between two cable clips.

The exact position of the nut doesn't matter.

⬢Carefully turn the printer on the PSU side.

⬢Take the single end of the PE (not the forked end) cable that is already installed on the printer. Guide the cable through the right cable clip.

⬢Take the free end of the PE cable guiding from the printer and line up the connector with one of the connector of the extended PE cable.

⬢Push the M3x6 screw and the M3w washer through the both connectors.

⬢Attach the joint of cables to the M3nEs nut in the extrusion profile and secure it by fully tightening the M3x6 screw.

⬢The free extended PE cable must be in the left position and lead freely outside the printer.

⬢Merge both PE cables and attach them with the zip tie to the left cable clip.

⬢Note two threaded screw holes in the silver power supply unit (PSU). Secure the extended ground connector to the "upper" hole using the M4x5 screw.

⬢Guide all PSU cables through the right cable clip.

⬢Slide the zip tie through the circular holes in the frame to create a loop on both sides of the frame so that the cable goes through both the loops.

⬢Start tightening the zip tie so it is snug and holds the wires on both sides. Be careful not to over-tighten the zip tie as it could damage the wires. Cut off the remaining part of the zip tie very carefully.

⬢Continue upwards and using another zip tie create the next loop.

⬢Guide the Z-axis cable and all cables from the PSU through the zip tie.

⬢Place the PE and power cables at the bottom of the bundle.

⬢Push the cable gently in the zip tie and tighten it so it is snug and holding the wires. Be careful not to over tighten the tie as it can cut the wires. Cut the remaining part.

⬢Continue guiding the cables toward the xBuddy. Include the Y motor cable into the bundle.

⬢Secure it with another zip tie to the frame.

⬢Carefully guide and fold the xLCD cable under the cable bundle. Do not include the xLCD cable in the cable bundle. Leave it free for now.

⬢M3x6 screw (1x)

⬢M3w washer (1x)

⬢Using the 3/32 PT screw, attach the power panic extended cable connector to the last (right) power terminal slot. Do not completely tighten the terminal screw! A few turns are enough for now, we will fully tighten the screw later.

⬢Connect the white connector of the power panic extended cable to the slot labeled PWR PAN. on the xBuddy board.

⬢Leave the black connector of the power panic extended cable free for now.

Note that most of the following steps are taken with a black PSU and without power panic extended cable. However, specific instructions will be provided if there are differences for the silver PSU.

⬢Pre-screw three 3/32 PT screws into the terminals on the xBuddy board. Do not tighten the screws completely, 3-5 turns will be sufficient.

⬢Secure all power cable connectors with the terminal screws. Tighten the screws firmly.

⬢Divide the cable bundle into two paths:

⬢Insert the zip tie through the bottom hole in the cable clip.

⬢Guide the cables from the PE cables, PSU cables and Power Panic cable around the left side of the cable clip.

⬢Guide the xLCD cable and motor cables around the right side of the cable clip.

⬢Very gently tighten the cables with the zip tie. Cut off the remaining zip tie.

⬢Push the zip tie through the frame under the Z motor left.

⬢Guide the Z motor left cable through the cutout in the frame to the xBuddy box.

⬢Carefully tighten the zip tie. Cut off the excess of the zip tie.

⬢Connect the Y motor to the second slot from the left. Guide the cable along the right side of the xBuddy box and behind the edge of the xBuddy board.

⬢Connect the Z motor cables to the third and fourth slots. The order of wiring does not matter.
