2.5 Safety instructions for I/O devices
Risk of damage to the device from connecting I/O devices
Fault caused by I/O devices
The connection of I/O devices can cause faults in the device.
The result may be personal injury and damage to the machine or plant.
• Only connect I/O devices which are approved for industrial applications in accordance
with EN 61000-6-2 and IEC 61000-6-2.
• I/O devices that are not hotplug-capable may only be connected after the device has
been disconnected from the power supply.
Danger due to regenerative feedback
Damage through regenerative feedback
A connected or installed component can cause voltage to be fed back to ground in the
device.
This can damage the device.
• Do not supply voltage into the device through connected or installed I/O devices, such as
a USB drive.
Prevent regenerative feedback.
Note on measuring the counter voltage
following when measuring the counter voltage:
Switch off the affected device and then insert the power plug.
Connect all cables from the system to the device and switch all components of the system
to active before starting the measurement.
