3.2.3 Connecting the electrical cables
Information on the procedure, as well as on connecting
cables and current requirements can be found in the
manual "CP system, installation and commissioning."
WARNING
Use only power units which guarantee reliable
isolation of the operating voltages as per IEC 742/
EN 60742/VDE 0551 with at least 4 kV isolation
resistance (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, protection against electric
shock (protection against direct and indirect contact) in
accordance with EN 60204-1/IEC 204 is guaranteed on
Festo valve terminals. Safety transformers with the ad-
jacent designation must be used for supplying PELV
networks. The valve terminals must be earthed in order
to ensure their function (e.g. EMC).
PLEASE NOTE
Check your EMERGENCY STOP circuitry, to see
which measures are required in order to place your
machine/system in a safe state in the event of an
EMERGENCY STOP (e.g. switching off the power
supply to the valves and output modules, switching
off the compressed air supply).
