Installing Extender Cables

This section applies to horizontal and Legacy Vertical carriers. For VerticalPLUS carriers, refer to “Extending LocalBus Power to Other Carriers.”

When carriers are installed on separate DIN rails, extender cables are used to extend LocalBus power. Extender cables connect to one-wide carriers on the left and right sides of the 2-wide, 4-wide, and 8-wide carriers.

Note

The 4-wide and 8-wide carriers must be left-aligned when using extender cables.

A standard installation uses one extender cable; however, dual extender cables can also be used. The following procedure is for a standard installation that uses one carrier extender cable.

To install carrier extender cables

  1. Install the right and left-side one-wide extender cable carriers by sliding together the 48-pin connectors on the sides of the carriers.
  2. Connect the 44-pin D-shell (male) connector on the extender cable to the top D-shell connector labeled A on the right-side carrier and fasten the retainer screws.
  3. Connect the 44-pin D-shell connector on the other end of the cable to the top D-shell connector labeled A on the left-side carrier and fasten the retainer screws.
