Note
Damage to the device in the event of a mix-up of the connecting pins.
• When establishing the load voltage supply for the IO-Link master port on the
CECC-S, make sure that only connecting pins X11.1 and X11.2 are used.

If the CECC is located at the end of the line, connect pin 2 and pin 7 using a terminating resistor.
A corresponding plug with terminal resistor (120 ohms/0.25 W) can be found in the
accessories
www.festo.com/catalogue.
