Cable block diagrams (CBDs) provide you with a full graphical environment for your front-end design. Apart from regular actions in a drawing such as zooming, selecting, saving, and so forth, you can perform the following actions:

Action

Description

Placing electrical Items

You can select an electrical item (a PDB, load, cable, and so forth) in the Electrical Index or Reference Data Explore and drag it to an open cable block diagram.

Local panels and junction boxes that contain circuits cannot be placed on cable block diagrams..

See also Use Reference Items in a Cable Block Diagram.

Moving items

Select an item and drag it to another location in the drawing. Save the drawing to keep the items you moved in their new locations. Note that this does not affect the data in your database.

Placing cables

Drag a cable from the Electrical Index, Electrical Engineer, or Reference Data Explorer to an open CBD.

When placing parallel cables, drag only one of the parallel cables in the set. The software represents parallel cables using a single line.

Filtering out cables

You can set a filter that instructs the software to hide specific cables. For details, see Filter Out Cables from a Cable Block Diagram.

Placing single-core cable assemblies

Select a single-core cable assembly in the Electrical Index or Reference Data Explorer and drag it to an open cable block diagram.

  • When dragging from the Electrical Index, instead of dragging a single-core cable assembly, you can drag one of the current-carrying cables belonging to a given single-core cable assembly.

  • All the current-carrying cables of an assembly are shown as one line in a CBD.

  • Selecting a single-core cable assembly in a CBD enables you to edit the properties of the individual current-carrying cables in the Properties window.

  • The grounding and neutral appear on the CBD as separate lines. You can connect them as you require.

  • You cannot place an assembly that has a cable which is connected to an equipment item that has not been placed on the current CBD.

  • The software uses the symbol used for the current-carrying cables to identify single-core cable assemblies in the drawing.

  • If you defined a cable formation macro in the symbol used for single-core cable assemblies, the software identifies the formation of an assembly according to the following formula:
    <Number of parallel power cables> multiplied by [<Number of current-carrying cores> multiplied by <formation of a single-core cable assembly>]
    Example: 2 x [3 x (1 x )1 x 240 mm2))]

Connecting and disconnecting cables

To connect a cable, first place it on a CBD and then drag one of the cable ends of to a connect point of an electrical item.

After connecting a cable to an equipment item in a CBD, the software retains the connection points on the equipment symbol for all other CBDs where this equipment is used. That is, when placing this equipment on another CBD, all the existing connection points are retained on the equipment symbol as they were during the original connection and it will not be possible to connect other cables using those connection points. The software stops retaining connection points of equipment symbols if you disconnect the equipment in a CBD. Also, the software does not retain the connection points after changing the symbol of connected equipment.

When connecting parallel cables, drag the end of the line that represents the parallel cables to a connect point of an equipment item.

To disconnect a set of parallel cables or a single cable, drag its end away from a connect point of an electrical item.

If the symbol to which you want to connect the cable does not have enough connection points, the software displays a message informing you that there is a shortage of connection points on that symbol.

Connecting a cable directly to a PDB

It is possible to drag a cable to a PDB in a CBD drawing and connect this cable to the PDB directly without a circuit. As a result, in the Common Properties of that cable, the name of that PDB will appear in either To or From connections of the cable. This will enable you then to make a physical connection to one of the circuits of the PDB.

Showing or hiding cable label leader lines

You can show or hide the leader lines of cable labels by selecting Show_Leader_Iconon the Smart Label Modification toolbar. When selecting a cable label in a drawing, the leader line is always visible. If you want to see the leader line of a cable when the cable label is not selected, select a cable label and then select Show_Leader_Icon on the Smart Label Modification toolbar. The leader line of that cable label remains visible after selecting another graphical element in the drawing. To hide the leader line, select a cable label and select Show_Leader_Icon on the Smart Label Modification toolbar again.

Placing connectors

To place a connector, select Connector on the Draw toolbar. For more details about various actions with connectors, see Toolbars and Ribbons.
See also Mark Auxiliary Graphics on a Cable Block Diagram to learn how to distinguish between plant items and auxiliary graphics in a CBD.

SHARED Tip A connector is a line that serves to connect items in a drawing. A connector is an auxiliary graphic that does not represent any plant item.

Connecting and disconnecting connectors

To connect a connector, first place it on a CBD and then drag one of its ends to an electrical item.

To disconnect a connector, drag its end away from the equipment

Connecting and disconnecting single-core cable assemblies

After placing a single-core assembly on a CBD, drag one of its ends to a connect point of an equipment item. This action connects all the other current-carrying cables belonging to that assembly on the selected cable end. You can see this association in the Cable Common Properties of each individual cable.

To disconnect a single-core cable assembly, drag its end away from a connect point of an electrical item.

Connecting equipment items in parallel

After placing the required equipment items and cables on a CBD, select a cable that hasn't been connected yet and then select an equipment item pair from the Parallel Pairs list on the Modify Connector ribbon. You can now drag the selected cable to one of the pertinent equipment items that you want to connect in parallel. For a detailed procedure, see Connect Equipment Items in Parallel.

Moving a connection point of a connected cable or connector

You can move a connection point of a connected cable or connector along the outer edge of the symbol to which the cable is connected. Drag the required connection point along the edge of the symbol. If you want to drag it to a point that is already connected by another cable, disconnect that cable first to make the connection point available for another connection.

Manipulating Smart Labels and macros

You can move and manipulate Smart Labels and macros in an open CBD. For details, see the following:

Entering and modifying item properties

Select an electrical item and then enter or modify its properties in the Properties window.

Inserting annotations and redlining

Add text labels, symbols, or watermarks to your CBD as annotations. Add text, linked symbols, circles, rectangles, and lines to your CBD as redlining. For more information, seeAnnotations and Redlining.

Removing items from a CBD

In an open CBD, right-click the item and then select Remove on the shortcut menu. Note that if you want to remove a cable, you must first disconnect it.

Renaming a document and entering revisions

In an open CBD and select Edit > Document Properties.

Saving a CBD as an external file

In an open CBD, select File > Save As.

Printing a CBD

Select File > Print.

  • Sometimes, after the software opens a drawing, the distance between connected items is either too long or too short, which results in an inappropriate display of connectors. To control the visual consistency of connectors, you can set a Clearance value that specifies the amount of space that the software will maintain between the connector and the connected element (also known as range avoidance). This action allows you to control the visual consistency of connectors that make right-angle turns just before they attach to a symbol.

  • To set Clearance, select a connector and then type the minimum distance from the symbols where you would like the first turn in the connectors to occur. Note that the default setting is zero.

  • Cable block diagrams do not allow you to make dual power source connections. You can make these connections in the Electrical Engineer. After making such a connection in the Electrical Engineer, the cable block diagrams generated for these items will display the dual power source connections correctly. You can, however, disconnect an item from an alternative power source in a cable block diagram.
