In hazardous areas software is installed via USB memory sticks (USB(i) drives).
You may only use USB memory sticks permitted for use by R. STAHL HMI Systems GmbH. These USB memory sticks are below and in general referred to by R. STAHL HMI Systems GmbH as "USB(i) Drives". Data may only be copied onto the Panel PCs and software may only be installed with these USB Drives.
•In hazardous areas, you may only use Ex-i certified memory sticks supplied by R. STAHL HMI Systems GmbH.
•In an industrial area, a permitted, non-ex memory stick may be connected to the current-limited USB interface of the Panel PC after having been connected to any PC.
•R. STAHL HMI Systems GmbH's USB(i) drives may also be connected to non-intrinsically safe interfaces, from where they may be used with Panel PCs of the MT-4x6 series.
If devices are connected to the power-limited USB interfaces that have not been approved by R. STAHL HMI Systems GmbH, protective elements may become damaged, thus compromising the current limitating of the interfaces.
In this case R. STAHL HMI Systems GmbH can no longer guarantee the current limiting of the device.
In safe areas, installation may also be carried out via hard disk, CD/DVD, etc. under the following conditions:
•the software is installed in the safe area
•the USB devices are connected to the Ex-e USB interfaces USB1 or USB3 (X5 or X7) with the VB-USB-INST1 connection cable.
