Connections
The modules must be mounted on the terminal box of the circuit-breaker or of the fixed part of the withdrawable
circuit-breaker, in the first free slot after the Ekip Supply module.
Information on the assembly is available on the website http://www.abb.com/abblibrary/DownloadCenter/, in
particular in the kit sheet 1SDH001000r0512.
An example with an E2.2 circuit-breaker in fixed and withdrawable versions is provided to the side.
The following is a view of the terminal box of E1.2 and E2.2-E4.2-E6.2 circuit-breakers with the relevant wiring

Access from the display
With the modules energized, and the Local Bus enabled, the presence of the modules on the terminal box
activates additional menus on the display.
To enable the Local Bus, you need to select "On" in the menu Settings - Modules - Local Bus.
The following table shows the path for accessing the configuration parameters of the modules from the
display:
