Overview

This section describes how to install and remove the controller with its expansion modules from a top hat section rail (DIN rail).

Installing a Controller with its Expansions on a DIN Rail

Step	Action
1	Fasten the top hat section rail (DIN rail) to a panel surface using screws.
2	Position the top groove of the controller and its expansion modules on the top edge of the DIN rail and press the assembly against the top hat section rail (DIN rail) until you hear the top hat section rail (DIN rail) clip snap into place.
3	Place 2 terminal block end clamps on both sides of the controller and expansion module assembly. NOTE: Type ABB8P35 or equivalent terminal block end clamps help minimize sideways movement and improve the shock and vibration characteristics of the controller and expansion module assembly.
