11.4.2.1 Connection variations for USB interfaces
11.3.1
Usage of USB Memory-Sticks
Only USB memory sticks that are certified according to
IEC/EN 60079-11 may be used !
In an industrial area, a permitted, explosion proof memory stick may
be connected to the Ex ib/ic USB interface of the HMI device after
having been connected to any PC.
If devices are connected to the I.S. USB interface that have not been approved by R. STAHL
HMI Systems GmbH, protective elements may become damaged, thus compromising the
intrinsic safety of the interfaces.
In this case R. STAHL HMI Systems can no longer guarantee the intrinsic safety of the device !
11.3.2
Usage of external USB devices
Not applicable to MT-5x6-A-*
Software may be installed with the aid of any external USB devices subject to the following
conditions:
The software is installed in the safe area.
The USB devices are connected to the USB interfaces USB1 or USB3 (X5 or X7) with the
VB-USB-INST1 connection cable.
