6.7 E XTERNAL DRIVES
By default, no drive for removable media (CD/floppy disk) is integrated in the device.
Instead, the system provides a USB interface, to which an external drive can be connected.
In this case you'd have to ensure that the used device is suitable for industrial
environments.
Warning:
Connecting or disconnecting external drives during operation is not admissible, since it
cannot be excluded that the drive might be in use while connecting or disconnecting it.
Data loss might result in the event of non-compliance!
