Installation

4.1

Overview

Introduction
In this chapter we will show you how to prepare and install the ET 200M components.
There are two configuration types for the ET 200M:
• Standard configuration with rail and bus connectors between the modules
• Configuration with active bus modules for the function "Change During Operation" and /
or "Redundancy"
To set up an ET 200M, you must take into account the mechanical and electrical
configuration. For more information, refer to the chapter "Assignment planning (Page 34)".
Open components
The modules of an ET 200M are open equipment. That means you can only install the ET
200M in housings, cabinets or electrical operating areas. These housings, cabinets and
electrical operating areas should only be accessible by means of a key or a special tool. Only
trained or authorized personnel should have access to the housings, cabinets or electrical
operating areas.
