Switching on the power supply
Warning
Use only power units which guarantee reliable electrical
isolation of the voltage supplies in accordance with IEC
742/EN 60742/VDE 0551 with at least 4 kV isolation resis-
tance(Protected Extra-Low Voltage, PELV). Switch power
packs are permitted providing they guarantee reliable
isolation in accordance with EN 60950/VDE 0805.
Remark:
By using PELV power units with Festo valve terminals, you can
ensure protection against electric shock (protection against
direct and indirect contact) in accordance with EN
60204-1/IEC 204. For supplying power to PELV networks you
should use safety transformers with the symbol shown here.
The valve terminal must be earthed in order to guarantee the
operation of certain functions (e.g. EMC).
Caution
The load voltage supply for the outputs/valves must be
fused externally with maximum 10 A (slow blowing). With
the external fuse you can avoid functional damage to the
valve terminal in the event of a short circuit.
