Electrical isolation
The integrated electrical isolation between the power section and the control
section is a protective separation (reinforced insulation) acc. to EN 61800−5−1.
To maintain this protective separation, it must be ensured that the external
24 V supply and all components connected to this supply also have a protective
separation (SELV/PELV) acc. to EN 61800−5−1.
