The USB type A interface is only intended for the connection of peripheral devices.
Do not use the USB type A interface for commissioning or maintenance.
USB 2.0 certified cable required
If you use a USB cable which is not USB 2.0 certified, errors may occur during data transfer.
Use only USB cables that are labeled "Certified HI-SPEED USB 2.0".
USB cable length maximum 1.5 m

Functional problem with USB port
If you connect an external device with a 230 V power supply to the USB port without using a
non-insulated installation, you may experience functional problems.
Use a non-insulated system design.
Excessive rated load on port
A USB device with too high a power load may possibly cause functional problems.
Observe the values for the maximum load of the USB interface. You will find the values in
the section "Technical specifications" (Page 225).
