Important!
Possible damage to USB interfaces or USB devices!
•
Peripheral USB devices can be connected to the USB interfaces. Due to the large number of
USB devices available on the market, B&R cannot guarantee their functionality. Functionality
is ensured when using the USB devices available from B&R.
•
Because of general PC specifications these USB interfaces should be handled with extreme
care with regard to EMC, location of cables, etc.
Important!
Possible malfunction of interfaces and touch screen!
If functional ground is not present, faults in interface communication and touch screen functionality
can occur.
The device is only permitted to be operated if properly grounded.
