Attention:
Only use power supply units for the system/sensor
and actuator supply that correspond to PELV (Protective Extra
Low Voltage) or SELV (Safety Extra Low Voltage). Power supplies
according to EN 61558-2-6 (transformers) or EN 60950-1 (switching
power supply units) fulfill these requirements.
