2.2.2 Installation guidelines
(1) General
The installation guidelines contain information about the interference free deployment of iC9200. There is the
description of the ways, interference may occur in your PLC, how you can make sure the electromagnetic
compatibility (EMC), and how you manage the isolation.
(2) What does EMC mean?
Electromagnetic compatibility (EMC) means the ability of an electrical device, to function error free in an elec-
tromagnetic environment without being interfered respectively without interfering the environment.
The components are developed for the deployment in industrial environments and meets high demands on the
EMC. Nevertheless you should project an EMC planning before installing the components and take conceivable
interference causes into account.
