14.6 Insulation, protection class, degree of protection and rated voltage
Distributed I/O system
282
System Manual, 12/2016, A5E03576849-AG
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
2
.
The installation location (e.g. enclosure, control cabinet) must have a protective conductor
connection that meets the standard to maintain protection class I.
Degree of protection IP20
Degree of protection IP20 in accordance with IEC 60529 for all modules of the ET 200SP
distributed I/O system, which means:
●
Protection against contact with standard probes
●
Protection against foreign objects with diameters in excess of 12.5 mm
●
No protection against water
Note
Use a BU cover
To meet the requirements of the degree of protection "IP20", fit a BU cover onto unfitted
BaseUnits.
To ensure touch safety, fit a cover onto the opening of the infeed bus contacts belonging to
the last plugged-in motor starter BaseUnit.
Rated voltage for operation
The ET 200SP distributed I/O system works with the rated voltage and corresponding
tolerances listed in the following table.
Note the supply voltage of each module when selecting the rated voltage.
