Protective grounding terminal as PE+ contact,
delivery status
(green-yellow)
Note
Depending on the type of component, some of the safety sockets listed may not be present. The
circuit design may contain additional safety sockets due to the use of different components.
The specified protection class and safe use can only be assured if laboratory safety cables supplied by Festo
Didactic are used.
