This procedure explains how to design a layout for a power distribution board. This design consists of several stages and it is based on the physical structure that has been defined for the selected PDB.

The first step in the design is to create a PDB layout drawing and associate it with the structure of the current PDB. Next, you place the appropriate cells in the layout grid by dragging a cell to the drawing.

Before you start this procedure, make sure that the physical structure of the current PDB has been defined. See Design a Power Distribution Board Structure.

  1. In the Electrical Index, expand the folder hierarchy Documents > PDB Layout Drawings.

  2. Right-click the PDB Layout Drawings folder and then on the shortcut menu select New PDB Layout Drawing.

  3. Right-click the new drawing and then on the shortcut menu select Document Properties.

  4. On the Document Properties dialog, select an appropriate template and set the scale factor, which determines how the PDB is actually displayed in the drawing.

  5. Right-click the drawing name in the Electrical Index and then on the shortcut menu select Open.

  6. In the Electrical Index, expand the folder hierarchy Electrical Equipment > Power Distribution Equipment > Power Distribution Boards and select an appropriate PDB.

  7. Drag the PDB from the Electrical Index to the open drawing. After you drag the PDB to the drawing, the software draws the PDB structure based on the definitions you entered on the Power Distribution Board Structure dialog. Also, the software associates the drawing with the current PDB. The software allows only one drawing to be associated with a PDB.

  8. In the Electrical Index, expand the hierarchy of the current PDB to display the existing cells.

    SHARED Tip Now you are ready to start placing the cells in the PDB layout. Prior to doing that, make sure that the size of all the cells has been defined. The cell size can be automated or defined manually. See Create a Cell.

  9. Drag each cell from the Electrical Index to the appropriate place in the layout grid. The software places the cell in the drawing and associates the cell with its location in the drawing grid.

    • The software represents the cells using a default symbol and a macro that specifies the cell name.

    • You can customize your own PDB and cell symbols or use the default symbols provided by the software.

    • The software determines the symbol size automatically based on the cell size.

    • You can specify the cell names based on the physical location of the cells within the PDB. The cells inherit and store in their properties all the spatial coordinates related to their locations. You can use these coordinates when defining the cell naming conventions.

    • When placing a cell in the drawing grid, the origin point of the placed symbol is always the upper left corner of the upper grid row taken by the symbol.

    • Make sure that you synchronize the size of your cell symbols with the size of the cells. When creating cell symbols, the symbol size has to be defined according to the original physical size of the cell. The software scales the macro fonts and x and y coordinates according to the scale factor defined on the Document Properties dialog. This way you will avoid a situation in which the software places the macro incorrectly or the macro size exceeds the size of the cell units.

  10. Save the drawing.

  • A PDB can have only one structure and be associated only with one PDB layout drawing.

  • After you place a cell in the grid, moving a cell to another place in the drawing grid is possible if that part of the grid is vacant, that is there are no other cells assigned to that part of the grid. To move a cell, select Edit > Move Cell and then drag the cell to another place in the grid.

  • To remove a cell from the layout drawing, select a cell in the layout drawing and then select Edit > Remove Cell. Removing a cell from a PDB layout drawing does not delete the cell from your plant. After you remove a cell from a PDB layout, the software dissociates the cell from the drawing and the place that used to occupy in the grid becomes available for other cells. If no other cells exist, you can delete the vacant rows from the PDB structure. See Design a Power Distribution Board Structure.

  • Save the PDB layout drawing in the file format that you require.

  • Deleting a PDB layout drawing, does not dissociate the PDB from its layout. Furthermore, the software still retains the association of the cells with their locations in the PDB layout. The PDB layout drawing serves only as a means to show the PDB layout in a graphical way. Therefore, if you want to redesign the structure of a PDB, open the associated PDB layout drawing and remove all the cells.

  • You can open an existing PDB layout drawing for a specific power distribution board by right-clicking a PDB in the Electrical Index and then selecting Associated Drawings.

  • The scale of PDB layout drawings is limited to 1:100.
