5.2.1 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.
