Insulation, protection class, degree of protection and rated voltage
Insulation
The insulation for the I/O modules is designed in accordance with the requirements of
EN 61131-2:2007. The insulation for the motor starters is designed in accordance with the
requirements of IEC 60947-1.
Note
In the case of modules with 24 V DC (SELV/PELV) supply voltage, galvanic isolations are
tested with 707 V DC (type test).
