Use the optional current limit module with the station battery to supply and limit the current
through older carrier auxiliary relays (such as KA-4 relays). This module is located on the inside
of the chassis. When viewed from the rear locate it by the following:
-
3U chassis: on the left-hand side of the frame next to the I/O System Module.
-
6U chassis: on the right-hand frame below the Power Supply Board.
For terminal block designations see the diagram below.
