Warning
•
Use only PELV circuits as per IEC/EN 60204-1 (protective
extra-low voltage, PELV) for the electric power supply.
•
Also observe the general requirements for PELV circuits
in accordance with IEC/EN 60204-1.
•
Only use power sources which guarantee reliable electrical
isolation of the operating voltage as per IEC/EN 60204-1.
