Scalar L: 12V Power supply installation

image_pdfimage_print

This page describes how to install the 12V power supply on the chassis.

12V power supply installation

List of parts

  • 4 M3x8mm screws
  • 2 M6x12mm screws
  • 2 M6 Tnut
  • 2 PSU holders (plastic parts)

Scalar L - PSU installationAt the beginning, your chassis should look like this

 

 

 

 

 

 

 

Scalar L - Montage de l'alimentationYou will need 2 of the PSU holders.

They will allow you to hold the PSU in place on your chassis

 

 

Scalar L - Montage de l'alimentation

Use 2 M3x8mm screws and hook the 2 holders using the top screw holes on the side of the PSU

 

 

 

 

The protection grid should be located on the opposite side of the plastic holders

Scalar L - Montage de l'alimentationOptional: you can add 2 more M3X8mm screws at the top back of the PSU

The middle holder cannot have any more screws.

 

 

 

 

 

 

 


Preferred Installation

 

Scalar L - Montage de l'alimentationDepending on the length of your PSU wires you might be able to place your PSU on the right side of your chassis. The IEC power plug connector should then be facing toward the back of your printer.

 

 

 

 

 

 

 

Scalar L - Montage de l'alimentationPlace the PSU so that the Power wires are exiting next to the square holder on the chassis.

 

 

 

 

 

 

 

 

Scalar L - Montage de l'alimentationUse 1 M6x12 screw and 1 M6 TNut to hold each PSU holders

Scalar L - Montage de l'alimentationThe 12V wires should be placed along the Vertical extrusion profiles.

On top they should ideally follow the path shown on this schematic.

Alternative

Scalar L - Montage de l'alimentationYou can also place your PSU on the left side of your chassis.

The IEC power plug should then be facing toward the front of the printer

 

 

 

 

 

Scalar L - Montage de l'alimentationThe 12V power wire (here in blue) should be placed along the vertical extrusion profile as shown on this schematic.

 

 

 

 

 

 

 


SSR installation

Scalar L - Montage de l'alimentation

  • Move or touch this component only when the heatbed power plug is removed from the power inlet.
  • Never touch or move this component when the printer is working and the heatbed power cord is plugged in.
