DANGER
The 24 V power supply is to be designed as functional extra-low voltage with protective
separation in accordance with EN60204-1, Section 6.4, PELV (with G ground).
Note
The connecting cable between the voltage source and the load current supply connector L+
and the associated reference potential M should not exceed a maximum length of 10 m.
