This chapter contains information for mounting the Bus node
CTEU on an I-port-compatible device (e.g. valve terminal with
I-port interface) and for installing this combination in a high-
er-level field bus system (network).
Warning
Danger of injury through uncontrolled movements of con-
nected equipment.
Make sure that electrical and pneumatic equipment are in
a de-energised and pressureless status.
Before working on the pneumatics:
Switch off the compressed air supply
•
Vent the valve terminal
•
Before working on the electrical components, e.g. before
installation or maintenance work:
Switch off power supply
•
In this way, you can avoid:
– uncontrolled movements of loose tubing
– accidental and uncontrolled movements of the connec-
ted actuators
– undefined switching states of the electronics
