6 Safety sockets

Unless otherwise indicated in the technical data, the following color coding applies for supply and signal
connections on components of the Festo Didactic Automation and Technology Learning System.
Color Function
Voltage greater than SELV
e.g. supply voltage of 90 to 400 V AC per conductor
external conductor L1
Voltage greater than SELV
e.g. supply voltage of 90 to 400 V AC per conductor
external conductor L2
Voltage greater than SELV
e.g. supply voltage of 90 to 400 V AC per conductor
external conductor L3
Voltage greater than SELV
e.g. supply voltage of 90 to 400 V AC per conductor
external conductor

(green-yellow)
Protective grounding terminal as PE+ contact, delivery
status
The specified protection classes and safe use can only be ensured if 4 mm laboratory safety cables supplied
by Festo Didactic are used. Depending on the type of equipment, some of the safety sockets listed may not
be present.
The protective grounding terminal is designed as PE+ contact. This connection provides a low-impedance,
safe protective grounding conductor connection. The mechanically incompatible connection prevents a
connection error with a 4 mm laboratory safety cable.
The operator bears the responsibility for any removal of this adapter. For this purpose, secure the adapter
against twisting with a 10 mm open-end wrench. Insert a 1.5 mm Allen key in the hole on the adapter.
Turning the Allen key to the right releases the detent mechanism of the adapter.
