12.5 Information on insulation, protection class, degree of protection and
rated voltage
Insulation
The insulation is designed according to the requirements of EN 61131-2: 2007.
Note
In the case of modules with 24 V DC (SELV/PELV) supply voltage, galvanic isolations are
tested with 707 V DC (type test).
Note
The ground/minus pole of the 24 V DC power supply is connected via the device with
functional ground (FE).
Pollution degree / overvoltage category according to IEC 61131
● Pollution degree 2
● Overvoltage category: II
Protection class in accordance with IEC 61131-2:2007
The distributed I/O system ET 200SP fulfills protection class I and includes parts of
protection class II and III. The CPU 1515SP PC2 is a part of protection class III.
The grounding of the mounting rail must meet the requirements for functional earth FE.
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 according to IEC 60529, i.e.:
● Protection against contact with standard probe
● Protection against foreign objects with diameters in excess of 12.5 mm
● No protection against water
