Switching on the power supply
WARNING
Risk of injury due to electric shock.
• For the electrical power supply with extra-low voltages, use only PELV circuits that guarantee a
reinforced isolation from the mains network.
• Observe IEC 60204-1/EN 60204-1.
The power supply to the valves is provided via the load voltage supply valves of the CPX terminal
(U
VAL
).
The power supply for the pressure switches and the vacuum generators is provided by the operating
power supply (U
EL/SEN
). After switching off the load voltage supply, the pressure switches continue to
be supplied with voltage for the valves of the CPX terminal (U
VAL
).
