Insulation
The insulation is designed in accordance with the requirements of EN 61131-2:2007.
Pollution degree/overvoltage category according to IEC 61131
● Pollution degree 2
● Overvoltage category: II
Protection class according to IEC 61131-2:2007
The ET 200SP distributed I/O system meets protection class I and includes parts of
protection classes II and III.
The grounding of the mounting rail must meet the requirements for a functional earth FE.
Recommendation: For a configuration immune to interference, the line for the ground should
have a cross-section > 6 mm
The installation location (e.g. enclosure, control cabinet) must have a protective conductor
connection that meets the standard to maintain protection class I.
