Connecting The As-Interface Bus And The Load Voltage - Festo CPA-GE-ASI-8E8A-Z Serie Manual Del Usuario

3.6 Connecting the AS-Interface bus and the load voltage

Warning
S Use only PELV (protective extra-low voltage) circuits
as per EN 60204-1 for the electric power supply.
S Also observe the general requirements for PELV
power circuits as per EN 60204-1.
S Only use power sources which guarantee reliable
electrical isolation of the operating voltage as per
EN 60204-1.
Through the use of PELV circuits, protection against
electric shock (protection against direct and indirect
contact) is guaranteed in accordance with EN 60204-1.
Note
The sensor supply gained from the AS-interface- power
supply must be protected against short circuits and
overload. It must not be connected with other
potentials (example, a common ground).
The valves (outputs) are always supplied with 24 V
additional supply, separate via the load voltage
connection.
