Observe when connecting
Note
Use of USB devices
•
Wait at least ten seconds between removal and reconnection of USB devices.
•
When using standard USB devices, note that their EMC immunity level is frequently
designed only for office environments. These USB devices are adequate for commissioning
and servicing purposes. Only industrial grade USB devices are permitted for use in the
industrial field.
•
USB devices are developed and marketed by their manufacturer. The manufacturer
provides support for these USB devices. The terms of liability of the individual vendors or
suppliers apply.
Note
Functional problem with USB port
Malfunctions may occur if you use a potential
-free plant installation and connect an external
USB device with its own power supply to the USB interface. In this case, use external USB
devices without their own power supply or a non
-isolated plant installation.
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 can find the values in the
section "Technical specifications of the IFPs (Page 124)".
Note
USB interfaces of the Ethernet Monitors
The
following applies to the USB interfaces of the Ethernet Monitors:
•
Only one USB device per USB interface may be connected.
•
Cascading of the USB interfaces, e.g. using a USB hub, is not supported.
3.5.7 Securing the cables
3.5.7.1 Securing cables at the IFP
Use cable ties to secure the connected cables to the strain relief plate:
Make sure that the cables are not crushed by the cable tie.
Possible fastening points are marked in the following figures.
The following figure shows an example of securing the cables to the strain relief plate of a
built-in device.
