1.5. Basic safety measures
WARNING
If damage can be seen on the faceplate of the dialog controller, the device
must not be operated any more! It must be disconnected from the supply
voltage immediately!
Besides the danger of injury owing to the visibly sharp edges, there is also the
risk of touching parts under high voltage. Contact with high voltage can still
occur even some time after the supply voltage has been shut off.

Working on the DC
Before beginning work on the Dialog Controller you must always
first ensure that the equipment is in a safe state,
then first switch the DC off, followed by the equipment, and
only then disconnect the DC from the equipment.
WARNING
Hazards due to unforeseeable functional and processing movements
when the Industrial PC is disconnected.
These can result in death, serious injury or extensive property damage.
All equipment components must be disconnected from the Dialog Controller
whenever the Dialog Controller is not being used for operational or control pur-
poses, e.g., during maintenance or during functional checks after repairs.
Lock out and tag out all equipment components after they have been
switched off!
