• Kodak^® Magnus^™ 400 II family
• Kodak Magnus 400 family

Background

This procedure describes how to remove the current power distribution board (PDB), and to install the improved PDB.

Requirements

• Hex key set
• Cross-head screwdriver

Procedure

This procedure includes the following sections:

• Before you begin
• (Optional) Uninstall the MCU/MCU II
• Removing the PDB
• Installing the improved PDB
• Completing the installation

Before you begin

1. In the Magnus 400 Controller software, open the front and rear doors.
2. Quit the Magnus 400 Controller software, and turn off the platesetter.
   Note: Make sure all the power switches on the D-box are in the OFF position.
   
   

(Optional) Uninstall the MCU/MCU II
Important: If the platesetter is a multi-cassette unit (MCU)/MCU II configuration, you must first uninstall the MCU/MCU II from the platesetter.

1. On the MCU/MCU II, remove the two connecting screws (one on each side) that connect the MCU/MCU II to the platesetter, and set the screws aside.
   
   
   
   
2. To enable access to the platesetter, carefuly slide the MCU/MCU II away from the platesetter. Make sure there is enough space between the MCU/MCU II and platesetter to perform tasks and that there is no tension on the connection cables.
3. If the cables interfere with performing the tasks, disconnect them.
4. When you finish the PDB installation, reconnect the MCU/MCU II cable connections, and then reconnect the MCU/MCU II to the platesetter.
   Note: For more information, see Installing the MCU II-Ready to the Platesetter in the MCU II and SCU II Installation and Upgrade Guide (731-01209A).

Removing the current PDB

1. At the rear of the platesetter, remove the rear panel and rear trapezoid.

2. Disconnect the fan cable from the D-box.
   
   
   
   
3. Remove the screw that secures the vacuum pump cooling unit to the mainframe, and remove the vacuum pump cooling unit.
   
   
   
   
4. Disconnect all the cables that are connected to the D-box.
   
   
   
   
5. Using a cross-head screwdriver, loosen the screws on the D-box cover, and remove the cover.
   
   
   
   
6. Disconnect all the cables connected to the PDB.
   
   
   
   
7. Remove the six screws that secure the PDB to the D-box, and remove the PDB.

Installing the improved PDB

1. Insert the improved PDB into the D-box, and secure it to the D-box with the six screws that you removed earlier.
2. On the improved PDB installed inside the D-box, reconnect all the PDB cable connections.
   Note: Each cable connection is a different size. Connnect each cable to the correct size Molex^® connector on the PDB.
3. At the rear of the D-box, reconnect all the cable connections.
   
   

   Connector	Connection on D-box
   J10	Drum vacuum
   J8	Loading vacuum
   J6	Power and communication
   J5	Solenoid
   J4	Interlocks and solenoid
   J2	Hall effect
   J1	Drum meter

   
   
4. Using a cross-head screwdriver, reinstall the D-box cover by tightening the cross-head screws that secure the D-box cover to the D-box.
5. Reinstall the vacuum pump cooling unit.

Completing the installation

1. Reinstall the front and rear trapezoids, the front and rear panels, and close all doors.
2. Turn on the platesetter, and start the Magnus 400 Controller software.
