8.5 Specifications concerning insulation tests, protection class, and rated
voltage for ET 200S
Test voltage
The insulation resistance is tested during routine tests using the following test voltage
according to IEC 61131-2:
Circuits with a rated voltage of U
other circuits or ground
Degree of Pollution / Overvoltage Category to IEC 61131
● Pollution level 2
● Overvoltage category
Protection Class
Protection class I in accordance with IEC 60536
Protection class IP 20
Protection class IP 20 according to IEC 60529 for all ET 200S modules i.e.:
● Protection against touch with standard test fingers
● Protection against foreign bodies with a diameter greater than 12,5 mm
● No specific protection against water
Rated voltage for operation
The ET 200S distributed I/O system works with the rated voltage and corresponding
tolerances shown in the following table.
ET 200S modules
Everything except motor starters
Static value: Generation as functional extra-low voltage with safety isolation in accordance with IEC 60364-4-41
