• Use for the electrical power supply only PELV circuits in
accordance with EN 60204-1
(Protective Extra-Low Voltage, PELV).
• Also consider the general requirements for PELV circuits
in accordance with EN 60204-1.
• Use only voltage sources that ensure a reliable electric
separation of operating voltage in accordance with
EN 60204-1.
Through the use of PELV circuits, protection from electric
shock (protection from direct and indirect contact) in
accordance with EN 60204-1 is ensured (Electrical equipment
of machines. General requirements).
The current consumption of a CPX terminal depends on the
