Note: The maximum number of terminal strips an equipment item (or equipment catalog item) can have may (optionally) be specified on the More Information window accessed from the Equipment Layout window. If you attempt to add a terminal strip when the maximum number of strips has already been added to an equipment item, a message is displayed to inform you of this. For example:

  • To add a Terminal Strip or an Earth Bar, do one of the following:

    • From the Equipment Layout window, right-click on any DIN Rail or existing component, and then select either Add Terminal Strip or Add Earth Bar as appropriate.

    • From the Equipment View context-sensitive right-click menu (after right-clicking on an appropriate equipment node), select either Add Terminal Strip or Add Earth Bar.

    The appropriate information window opens.

Terminal Strip No/
Earth Bar Name

Enter any unique value for the current equipment as the Terminal Strip number or Earth Bar name.

No. of Terminals

Defines the number of terminals in the strip/bar.

Note: The maximum number of terminals that an equipment item (or equipment catalog item) can have on a strip may (optionally) be specified on the More Information window accessed from the Equipment Layout window. If you attempt to add terminals in excess of this, a message is displayed to inform you about this

First Terminal No

Defines the starting terminal marking. Wiring Manager will create incremented terminal markings for all subsequent terminals.

Wiring Manager does not support auto-numbering of any terminals except for simple incremental numerical (count). However, once the terminal strip/earth bar has been created, users can edit individual terminal markings in the Terminations User Interface.

Field Wires

Terminate on Right

Is only valid when using Wiring Rules to terminate field cables on equipment terminal strips/earth bars. When checked, field cables are terminated on the right side of this terminal strip/earth bar. When unchecked field cables are terminated on the left of the terminal strip/earth bar.
