1.2.3 Connecting the cables and plugs to the connection blocks

Festo P.BE-CPX-EA-EN en 1105h
Sensors and actuators must only be connected to the
CPX I/O modules at the connection blocks. In this way,
e.g. when an electronic module is replaced, the plugs and
cables remain fitted in the connection block.
Warning
Uncontrolled movements of the connected actuators and
uncontrolled movements of loose tubing can cause injury
to human beings or damage to property.
Before carrying out installation and maintenance work,
switch off the following:
– Compressed air supply
– The operating and load voltage supplies.
The protection class of the I/O modules depends on the con-
nection block used as well as on the plugs and protective
caps used. Instructions can be found on the following pages
and in the Appendix A.1.
Use plugs and cables from the Festo range for connecting
sensors and actuators (see Appendix B.3).
