5.3 Electrical configuration of the ET 200AL
Electrical isolation
When electrically configuring the ET 200AL distributed I/O system, there is electrical isolation
between:
● Load voltage 2L+ and all other switching parts
● Communication interfaces (PROFINET/PROFIBUS) of the interface modules and all other
switching parts
● ET-Connection and all other switching parts
The following images show the potential conditions of the modules of the ET 200AL
distributed I/O system.
